Bay State Perennial Farm is known for its wide selection of perennials. Plants are listed alphabetically by their latin names and can be located by clicking on the first letter of the plant name in the alphabet above.

Phlox stol Sherwood Purple 400

Phlox stolonifera ‘Sherwood Purple’

Pachysandra terminalis ‘Green Sheen’     Similar in most respects to common pachysandra except the foliage has a shine that holds all season. Somewhat more upright in habit. It’s hard to argue with success and this plant succeeds as groundcover almost everywhere,- the Arborvitae of the perennial world! Around 1’ tall. For shade. Deer resistant. Zone 4.

PAEONIA (Garden Peony)

Lactiflora and hybrid double peonies

Paeonia ‘Alan Rogers’ New 2018     Pure white, double flowers with a strong fragrance and extra strong, flower-supporting stems. 32” high. Blooms early to mid season.

Paeonia Bunker Hill 175

‘Bunker Hill’   An heirloom variety with double, cherry-rose flowers that are delicately edged in white. Fragrant. 32” tall. Blooms mid-late season.

Paeonia Coral Sunset 175

‘Coral Sunset’    Semi-double coral blossoms with rose overtones and a fluffy boss of deep yellow stamens. Lightly fragrant and long lasting in fresh bouquets. 28” tall. Blooms late spring.

    Dr. Alexander Fleming’     Fragrant, fully double pink flowers in early summer. Many side buds extend the bloom time. The central petals have a tendency to curl inward, creating a more dense, fuller flower.. 30" tall. Blooms early summer.

    ‘Festiva Maxima’   A classic double white peony introduced in 1851 and still widely favored by gardeners. Blooms late spring to early summer. 36” tall.

Paeonis Mons Jules Elie

Paeonia ‘Mons. Jules Elie’    Broad, smooth, rose-pink guard petals surround a mound of incurving, silvery-pink petals, giving the flower a slight two-toned effect. 30” tall, blooms early summer.

    obovata see under woodland flowers

    ‘Paula Fay’     Semi-double vivid pink flowers on strong stems. Foliage emerges early, followed by early season flowers. APS Gold Medal Winner. 34" tall.

Paeonia lactiflora _Pink Parfait_175

Paeonia ‘Pink Parfait’     Ravishing, medium pink, rose-like double blossoms with silver edges make this variety shine in any garden! Blooms late season . Very fragrant. 36ins. tall.

Paeonia Pink Hawaiian Coral

‘Pink Hawaiian Coral’    Fragrant, simi-double coral flowers blending to soft pink at the tips. 36ins. tall, strong stems. Blooms in June. A beautiful peony that always gets lots of attention in our border.

    ‘Raspberry Sundae’      Huge, full blossoms up to 6ins. across are delightfully fragrant and great for cutting. Pale pink guard petals surround a fluffy vanilla to blush pink center flushed deeper pink on top. 30ins. tall. Blooms early summer.

    tenuifolia New     (Fernleaf Peony)  Dark red, single flowers atop deeply dissected, thread-like foliage that is completely unlike the foliage of other garden peonies, up to 2' tall. Blooms early and may go dormant in early summer. Tolerates drier conditions better than most peonies. Native to Asia Minor, Caucasus and South East Europe where it grows in dry meadows. Roots are large, tuberous, allowing plants to store water for use during dry periods. Not common in garden. Confers lots of pride of ownership on gardeners who grow it. For sun to light shade. Conflicting cultural information exists, some recommending rich, evenly moist soil, while others suggest that sparse, average to dry conditions are best. Something in the middle is probably the safest bet, avoiding overly moist, highly enriched sites. In any case, excellent drainage is important. Our plants will be five years old in spring of 2018 and may require another year to bloom. Deer resistant. Zone 5(4).

    ‘Sorbet’     An exceptionally nice, full bomb type flower with petals in a mix of bright pink and canary yellow.  28in. tall, mid-season bloomer.

Intersectional Peonies

Intersectional peonies are the result of crossing herbaceous and woody or tree peonies. They retain the best qualities of both parents including: large flowers in unique colors, strong weather resistant stems, longer bloom time, extreme winter hardiness, and increased vigor. Plants should not be pruned to the ground in fall as lower portions of the stem carry next years’ buds. Buds will also initiate from the crown as do herbaceous peonies.

Paeonia Bartzella

‘Bartzella’   Huge, 6-8”, semi-double to double, pastel yellow flowers with a small rose purple flare in the center and a pronounced sweet scent. Blossoms are neatly spaced on the top and sides of the sturdy clump of healthy green, tree peony-like foliage. 3’ tall, with best bloom in full sun with rich, evenly moist but well drained soil, pH around neutral. 

    ‘Cora Louise’   Hug, 8”-10”, semi-double, lightly fragrant, white flowers with deep lavender purple flares and a prominent tuft of yellow stamens. Blossoms are neatly spaced on the top and sides of the sturdy clump of healthy green, tree peony-like foliage. A mature specimen can produce 50 flowers! 24”-36” tall. Blooms in late spring.

    ‘Julia Rose’   Soft semi-double apricot flowers blending to a deeper pink at the edge of the petals. Very sturdy, upright habit. 36" tall. Blooms midseason.

    ‘Sequestered Sunshine’    7", single to semi-double , bright canary yellow blossoms on strong stems. Flowers are accented by a central boss of showy yellow stamens with hints of red, fragrant excellent for cutting. Forms a dense, sturdy clump of dark green, attractively dissected foliage, 3'-3' tall. Blooms late spring. Zone 4.

    ‘Yankee Doodle Dandy’     Semi-double, sometimes double, deep pink flowers measuring up to 6” across and representing a new color for Intersectional Peonies. Very heavy blooming on exceptionally strong stems, with disease resistant foliage that looks good all season long.

Japanese and Single Peonies

    ‘Krinkled White’     Single white flowers with bright gold stamens in the center. Strong stems that do not need staking. A solid, consistent garden performer. 32” tall, begins blooming early to mid June.

    ‘Leslie Peck’    Deep bright pink flowers with large, pink puffy, centers. Fragrant. Japanese-type flowers open early in the season, 34” tall.

Paeonia Pacifica 175

‘Pacifica’     Apricot/pink flowers with large tufts of golden stamens in the center. 34” tall, Japanese type. Blooms early-mid season.

Tree Paeonia (suffruiticosa)

Paeonia suffruiticosa Tree Peony    We’ve grouped the tree peonies with their herbaceous cousins to eliminate unnecessary clicking back and forth between web pages and because it just seems to make sense to present them together. But make no mistake, tree peonies do have stems of real wood. Plants seldom get much taller than 4ft., appreciate a rich, slightly basic, moist, well-drained soil, and do very well in light afternoon shade. Full sun is certainly okay, but here water becomes more of an issue. Pruning should be avoided unless plants become misshapen, at which time they may be cut back to a foot or so to encourage the development of new shoots. This should not be done routinely, and actually, is best avoided altogether unless plants become an unshapely mess. These are not difficult plants to grow when provided with conditions even remotely approaching ideal. We’ve had our tree peony for many years and I defy anyone to accuse us of pampering it. When we remember to do it, a little lime, fertilizer and compost get turned under in spring.  For this meager effort we’re rewarded every year with two weeks of huge, beautiful blooms during late spring/early summer.  Zone 4. 08-FullSun-s 07-PartialShade-s 04-Drip2 scissors

Paeonia suff Hanadaijin 175

Paeonia suff. ‘Hanadaijin’     Very large, semidouble, purple flowers with darker centers. Later blooming.

    ‘Hanakisoi’    Apricot-pink petals with a soft pink edge. Semi-double blossoms. 4’-5’ tall Blooms late spring.

    ‘Meikouhou’     (Treasure of Emperor) Double white flowers with just a suggestion of pink, especially toward the center. 

    Pink Flowered   (Tree Peony) Tree peonies do have stems of real wood. Plants seldom get much taller than 4ft., appreciate a rich, basic, moist, well-drained soil, and do very well in light afternoon shade. Full sun is certainly okay, but here water becomes more of an issue. Pruning should be avoided unless plants become misshapen, at which time they may be cut back to a foot or so to encourage the development of new shoots. This should not be done routinely, and actually, is best avoided altogether unless plants become an unshapely mess. These are not difficult plants to grow when provided with conditions even remotely approaching ideal.

    Red Flowered   (Tree Peony) Tree peonies do have stems of real wood. Plants seldom get much taller than 4ft., appreciate a rich, basic, moist, well-drained soil, and do very well in light afternoon shade. Full sun is certainly okay, but here water becomes more of an issue. Pruning should be avoided unless plants become misshapen, at which time they may be cut back to a foot or so to encourage the development of new shoots. This should not be done routinely, and actually, is best avoided altogether unless plants become an unshapely mess. These are not difficult plants to grow when provided with conditions even remotely approaching ideal.

    Purple Flowered     (Tree Peony) Tree peonies do have stems of real wood. Plants seldom get much taller than 4ft., appreciate a rich, basic, moist, well-drained soil, and do very well in light afternoon shade. Full sun is certainly okay, but here water becomes more of an issue. Pruning should be avoided unless plants become misshapen, at which time they may be cut back to a foot or so to encourage the development of new shoots. This should not be done routinely, and actually, is best avoided altogether unless plants become an unshapely mess. These are not difficult plants to grow when provided with conditions even remotely approaching ideal.

Papver orientale(Oriental Poppy)     All oriental poppies decline after flowering, usually to the point of complete dormancy by summer. Plants will reemerge with cooler fall weather.  Combine with Gypsophila (Baby's Breath) or some other leafy, later-blooming plant to fill in the gap. 08-FullSun-s 04-Drip2 01-Hummingbirds scissors

    orientale ‘Beauty of Livermere’     A big, bold, red poppy. One of the best reds. 2-3ft. tall. All oriental poppies decline after flowering to the point of complete dormancy by summer. Plants will reemerge with cooler fall weather or they may remain dormant through winter and regrow in spring. Combine with Gypsophila (Baby's Breath) or some other leafy, later-blooming plant to mask dormant plants. For sun with average to rich, welll-drained soil. Very hardy, zone 2. Deer resistant.

Papaver Queen Alexandra

Papaver orientale ‘Queen Alexander’     Salmon pink with black centers. 2' high, blooms May-June.

    orientale ‘Prince of Orange’     Large, 4”-5” wide flowers the color of tangerines. 30” tall, late spring-early summer. Attracts hummingbirds, resists rabbits and deer. Zone 3.

    orientale ‘Royal Wedding’   Pure white flowers with black centers, 2’ tall, blooms May-June. Oriental poppies decline after flowering to the point of complete dormancy by summer. Plants will reemerge with cooler fall weather or they may remain dormant through winter and regrow in spring. Combine with Gypsophila (Baby's Breath) or some other leafy, later-blooming plant to mask dormant plants. For sun with average to rich, welll-drained soil. Very hardy, zone 2. Deer resistant.

    Other Poppies

Papaver miyabeanum ‘Pacino’     Low, dense rosettes of hairy, mint green leaves give rise to numerous , 6”-8” tall stems bearing 1”-1” wide, bright, sulphur yellow flowers with the wonderfully shear, paper-thin texture so characteristic of all poppies. Blooms May-June and should be given a sunny spot with average, well-drained soil, preferably in crevices between rocks, or actually in a rock garden or in a well-drained spot at the front of the mixed border. Somewhat short lived, but a reliable self-seeder. Our plants always forgo the improved, enriched conditions of our borders and, instead, choose to seed into the harsh, dry, infertile conditions of the stone pathways between borders. A delightful, bright, bold spot of color in the early spring garden. Deer resistant. Zone 3.

Papaver nor. ssp. islandicum 175

nordhagenianum ssp. islandicum (radiatum ssp. radiatum) (Arctic Poppy)     This very long name belongs to the little orange poppy that has graced our borders for many years. We think we have the correct name, but whatever the name, it’s a charmer, with orange, crepe paper-textured flowers over gray-green foliage, 18-24".  Blooms off and on all summer long. Self sows. Very hardy.

    nudicaule ‘Champagne Bubbles’    Especially large, satiny flowers in a wide range of pastel colors held on 18” stems above rosettes of light green foliage. Bloom begins in late spring and continues for many weeks. Best sited in average soil, full sun. Plants become quite drought tolerant once established. Flowers add great interest to arrangements if stems are taken just as buds begin to open. Dead-heading encourages more bloom. Iceland Poppies are biennial which usually self seed and keep the population going from year to year; so be sure to leave some seed pops. Attracts hummingbirds. Rabbit and deer resistant. Zone 2.

Penstemon dig Blackbeard 175

Penstemon digitalis ‘Blackbeard’    An improved ‘Dark Towers’ with stronger stems that remain upright all season, deeper lilac-purple flowers that begin blooming in June, and deeper purple foliage that keeps its color even in full sun. 3’ tall. Attracts hummingbirds and butterflies. Nice for cutting. Zone 3.

    digitalis ‘Husker Red’     Bronze-red foliage provides striking contrast to masses of white flowers, 30". 1996 Perennial Plant of the Year. Zone 3.

    digitalis ‘Pocahontas’     Larger lavender-pink flowers than either 'Dark Towers' or 'Husker Red'. Also, the deep red foliage is carried with a more upright orientation on dark colored, extra strong stems that hold the flowers in a strong, upright clump. 3'-3' tall. Blooms in early summer but the attractive foliage is eye-catching for the entire season, with or without flowers. Attracts hummingbirds, cuts well. Zone 3.

Penstemon Red Riding Hood 175

Penstemon ‘Riding Hood Red’     18-24” tall x 18” wide with an abundance of large, white lipped, coral-red flowers from late spring through summer. Flowers are carried on strong, upright stems that are excellent for cutting and very attractive to hummingbirds. Showy and easy to grow in average or better well drained soil. Though tolerant of a range of soils, plants require excellent drainage and will languish with excess moisture. Though drought tolerant, plants should receive occasional watering during prolonged dry periods. Stunning to look at, but watch out for incoming hummingbirds while you’re enjoying the view! Zones 5.

Perovskia atriplicifolia

Perovskia atriplicifolia (Russian Sage)     Finely textured, aromatic, silver-gray foliage topped with long spikes of purple flowers in late summer, persisting for many weeks. Plants have an airy and relaxed form. Full sun and good drainage are essential. Cut back in spring to no more than 1ft. It has been our experience that going lower than 1 ft. greatly impedes the plants ability to fully regrow during the season.  Hardy to zone 5.  08-FullSun-s 05-Drip 04-Drip2 01-Hummingbirdsscissors

Perovskia a. ‘Blue Jean Baby’ New 2018    Compact silvery-green foliage with a strong upright habit, 2-3’ tall.  Lavender-blue flowers of especially heavy substance begin blooming in mid summer and continue through summer. Its breezy, airy texture commend this Russian Sage as an unrivaled filler plant in the sunny border. Very drought tolerant. Attracts butterflies, deer resistant. Zone 4. 

Perovskia a. ‘Little Spires’    Selected for its shorter more upright habit and its longer bloom period. Grows 2 1/2ft.-3ft. tall. For average, well drained soil, in full sun. Attracts hummingbirds, deer resistant. Makes an interesting addition to cut arrangements. Zone 4.

Persicaria f Painters Palette 175

Persicaria filiformis ‘Painter’s Palette’      From seed, so the variegation is different on every plant, each displaying a unique combination of the colors in unique blends of red, ivory, yellow and pink, splashed over the green leaves. Not all colors are present on every plant but every combination is attractive no matter how many colors are in the mix. These make great fillers in the shade border and, after a season of self-seeding, will populate large areas with their pretty foliage and their understated but quite effective panicles of tiny, bright red, bead-like flowers. Blooms in late summer for many weeks. Prolific self-seeders but unwanted volunteers are easily pulled. I've spent many a pleasant time culling through a bunch of seedlings picking out the most colorful ones for growing on. Easy in average soil in part to full shade. 2' high. Zone 4.

 

Persicaria polymorpha

Persicaria polymorpha    Fluffy, creamy-white plumes all summer long over strong stemmed, upright, non- spreading mounds of foliage. Its long bloom period, strong upright habit and ease of culture commend this plant as a first rate garden specimen. Several years ago when it was new on the gardening scene, polymorpha created a good bit of excitement, and if you’re looking for a large, pest free perennial with good form and season-long bloom, then this might be just your plant. 5-6ft. high. Zone 4.  

Phlomis russeliana   This native of the mountains of Syria and Turkey is treasured for both bloom and attractive foliage. Pale yellow flowers bloom, in whorls, up and down the 36” stems with heaviest bloom in spring followed by sporadic bloom through summer. The large, olive green, spade-shaped leaves are aromatic and somewhat fuzzy. For sun with average soil. Drought tolerant. Deer resistant. A terrific mid-border perennial valued for its flowers and its unique architectural form. Zone 4.

Taller Growing, Border Phlox

Phlox paniculata Bambini® ‘Desire’ New 2018     A breakthrough in garden Phlox, this compact selection is only 1’ tall but gives up nothing in flower power with its massive display of hot, pinkish-purple flowers in July and August. At only 1’ tall it vies with bedding plants at bringing bright, long lasting color right down to the front in the border. Also tucks nicely into mixed containers. Best in sun with average to rich, evenly moist but well-drained soil. Mildew resistant, attracts butterflies and hummingbirds, cut well. Zone 4.

Phlox pan. 'Blue Paradise'

PHLOX paniculata ‘Blue Paradise’    This is the bluest garden phlox I’ve seen.  Flowers open a unique, smoky-blue, then take on a bit of red, finally resolving to a nice blue/purple.  With average, even moisture, plants bloom for most of the summer and demonstrate good mildew resistance. It was recommended to us that the addition of extra amounts of lime to the soil can greatly reduce the presence of powdery mildew.  We’re trying it and it seems to be helping. So, more lime, together with a fastidious cleanup in fall, are two non-chemical measures that can help combat the scourge of mildew.

    paniculata ‘Cherry Red’(Peacock Series) New 2018      Bred for heat tolerance, disease resistance and good branching. Sturdy plants, reaching 2-3’ high carry large, fragrant, cerise-red flowers all summer. Attracts butterflies and hummingbirds. Zone 3.

    paniculata 'David'    4-5', white, fragrant, mildew resistant - this plant has it all. Perennial Plant of the Year 2002.

Phlox pan Delilah

Phlox paniculata ‘Delilah’     Dark red/purple flowers on strong, shorter stems, only 2’ tall. Mildew resistant. Attracts butterflies and hummingbirds. Nice for cutting. Zone 4.

    paniculata ‘Flame Coral’     Low-growing, naturally compact and mildew resistant, with bright coral-pink blooms that really stand out in any garden. Only 15-18" tall and nicely suited for mid-border placement and for containers. Fragrant, attractive to hummingbirds and butterflies. Best in sun, with fertile, reasonably moist, well-drained soil. Very showy for many week in early to mid summer. Deadheading will encourage additional bloom.

    paniculata ‘Flame Red’ New 2018     Low-growing, naturally compact and mildew resistant, with bright red blooms that really stand out in any garden. Only 15-18" tall and nicely suited for mid-border placement and for containers. Fragrant, attractive to hummingbirds and butterflies. Best in sun, with fertile, reasonably moist, well-drained soil. Very showy for many week in early to mid summer. Deadheading will encourage additional bloom.

Phlox pan Flame Wt Eye 175

Phlox paniculata ‘Flame White Eye’     A low growing summer phlox, 'White Eye' blooms in July-August with large, fragrant panicles of white flowers stamped with red at their centers. Only 15-18" tall and perfectly suited for mid-border and for containers. Fragrant, attracts hummingbirds and butterflies, and, though they have a relatively short vase life, while they last they contribute a delightful fragrance and a bodacious look to cut flower arrangements. Zone 4.

    paniculata ‘Glamour Girl’    Bright green, healthy foliage shrugs off powdery mildew with ease and looks great all season. Large panicles of glowing , hot coral-pink, fragrant flowers on dark colored stems. 32” tall, blooms early-mid summer through late-summer. Zone3.

Phlox pan Jenna 175 best

paniculata ‘Jeana’     Intriguing, tiny ("), pink flowers are tightly crowded into golf ball sized clusters which, in turn, are combined with many similar clusters to form a single large flower panicle. Very different, possessing that special allure of the miniature. Grows quite tall with clumps in our border reaching 5 to 6' in height. Very high mildew resistance.

    paniculata ‘Nicky’     3-4ft. tall with deep, luscious, magenta-purple flowers, mildew resistant. A beautiful, standout color that attracts much attention all summer long.  Hard to capture in words the intense, brilliant, burgundy-purple color of these flowers. 

Phlox x Minnie Pearl 175

x 'Minie Pearl'   Thought to be a naturally occurring hybrid between Phlox maculata and Phlox glaberrima, ‘Minnie Pearl’ blooms in early summer with large, pure white, fragrant panicles that attract lots of butterflies. Height is relatively low at 18” high and foliage is of the P. maculata type, long,narrow and waxy,exhibiting strong mildew resistance, (much like Phlox m. 'Miss Lingard'). Large, glistening white panicles cover the clean foliage during early through late June. Has the look of a Garden Phlox, without the mildew. Zone 5.

Lower Growing Phlox

Phlox divaricata ‘Blue Moon’    Drifts of deep blue fragrant flowers in May, one or two weeks before P. stolonifera. This spring ephemeral mixes well with other woodland wildflowers and ferns. Native to eastern US. Zones 3-9. 12-14 in. Part sun to shade, moist soil.

Phlox stolonifera (Creeping Phlox)    Low, modestly spreading foliage from which arise 12in. flower stems with 2 or 3 blooms per stem. Probably the most shade tolerant phlox and a valuable source of color in the woodland garden where its spring bloom establishes a soft, ethereal presence. Zone 2. 08-FullSun-s 07-PartialShade-s 04-Drip2 02-Butterfly

    stolonifera ‘Sherwood Purple’     Rich, deep purple flowers are held on sturdy stems 6-10" above thick, stoloniferous foliage mats. Flower color is intense, considered by many to be the best of the stolonifera type phlox. Valued for its eye-catching floral effect that casts an enchanting spell over the woodland garden for several weeks in early spring, and for its spreading foliage mats that are suitable for modest ground cover over smaller areas. Shearing off flower stems after flowering encourages thicker foliage mats. Provide average or better soil with reasonable moisture in part to full shade, or even sun, with sufficient moisture. Becomes more drought tolerant when established. Native to the Appalachians. Zone 5.

Phlox subulata ‘Emerald Cushion Blue’    More compact, with lavender-blue flowers over emerald green foliage in May.

Phlox subulata ‘Emerald Pink’    Clear pink flowers in May over dense mats of emerald green foliage. Zone 3.

Phlox subulata ‘Purple Beauty’ New 2018    Intense deep plurple flowers over compact, spreading foliage. Blooms April-May and adds a lot of "bling" to borders and rock gardens with flowers of a better purple than previously available. Full sun, average, well-drained soil. When blooming has finished, an occasional pruning back will maintain a dense foliage mat without the dead zones that may develop over time.

Phlox subulata ‘Snowflake’    Pristine white flowers over neat, 4" high and spreading, evergreen foliage. The latest variety to bloom, April-May.

Phlox sub Violet Pinwheels 175

Phlox subulata ‘Violet Pinwheels’ New 2018      Flowers in a beautiful shade of medium blue cover the dense, compact foliage mats in early spring, snapping the garden out of its winter doldrums with a blast of startling color! 6” tall with a spreading habit.

Physostegia (Obedient Plant, False Dragonhead)     3-4ft. tall, vigorously spreading clumps with spikes of pink or white, snapdragon-like flowers for a long stretch in summer. Will spread out of control in a year or two, at which point all but a few sprigs should be dug out and tossed. This is a chore we’re willing to perform in return for handsome, carefree, cutflowers all summer. Neutral or higher pHs suit them as does an even moisture level. Zone 3. 08-FullSun-s 07-PartialShade-s 04-Drip2 03-Drip3 

Physostegia virginiana 'Miss Manners'

Physostegia virginiana 'Miss Manners'     A clump-forming selection that displays excellent garden manners by not running rampant through the garden, invading its border companion’s territory. A good source of white flowers all summer. 2' high with glossy green foliage. Attracts butterflies and hummingbirds, deer resistant. Cuts well. Zone 3. 

Phyteuma scheuchzeri   This is a tough plant to describe but one that's well worth seeking out. First of all, it's related to the Bellflowers but you'd never know it except for the gorgeous deep blue color of its flowers. The shape of the flowers is very distinctive,-which should not be taken to mean that they're "odd" or merely "curious-looking", because, in fact, they are very beautiful. They're roundish, with many spiky, tubular, deep blue "structures" encircling a central orb, somewhat similar to Echinops but more loosely arranged. Foliage is grass-like, blue/green in color, tufted and modestly spreading. Flowers are attractively presented above the foliage on 8" stems, blooms over a long period, June-July. Suitable for the rock garden or any sunny, evenly moist, well drained spot. Zone 6, and 5 with snow or some other protection. I've carried it over for several years without protection here at Bay State, zone 5 on the line between a & b.

Platycodon (Balloon Flower)     Long lived, long blooming and pest free, balloon flowers are true low maintenance perennials.  Plants are late to emerge in spring so take care not to accidentally dig them out or mash them under foot. Large, inflated buds that always remind me of miniature hot air balloons open to reveal 2-3in. wide, five petaled flowers that, depending on variety, are either blue, white or pink in color and single or double in form. Again, depending on variety, plants can range in height from 6ins. up to 3ft. tall. Begins blooming in mid summer and continues for many weeks. Zone 3.

Platycodon g mar

    grandiflora ‘Mariessii’     This is a beautiful as well as useful, intermediate sized balloonflower, 2-3ft. tall. When the dwarf types are just too low, that's when 'Mariesii' fills the bill. Its the perfect size for mid border where its large flowers provide those much needed blue-purple tones in late summer. Blooms July -Aug. Combines beautifully with Coneflowers, Rudbeckias and Baby's Breath.

    grandiflora ‘Hakone Blue’    Semi-double blue flowers on medium tall, sturdy stems, 1-2" tall. The large blue flowers appear mid to late summer, July-August, providing strong blue tones to offset the many yellow blooms so pervasive at this time of year. Platycodons are beautiful, long-lived and pest free plants, and are generally considered to be among the top 10 best garden perennials. They also make excellent cut flowers. Grow in medium rich, reasonably moist but well-drained soil. They attract butterflies and are deer resistant. Zone 3.

    grandiflora ‘Hakone White’     Semi-double white flowers on medium tall, sturdy stems, 1-2" tall. The large blue flowers appear mid to late summer, July-August, providing soothing white flowers to offset the many yellow blooms so pervasive at this time of year. Platycodons are beautiful, long-lived and pest free plants, and are generally considered to be among the top 10 best garden perennials. They also make excellent cut flowers. Grow in medium rich, reasonably moist but well-drained soil. They attract butterflies and are deer resistant. Zone 3.

Polemonium (Jacob's Ladder)      Foliage is most heavily concentrated at the base, thinning out as it rises up the flower stalks. The placement of the leaflets on the long, compound leaves resembles rungs on a ladder, thus the common name. More commonly blue but also white, 3/4in.-1in. flowers occur in loose clusters conspicuously elevated above the foliage where they make a very pleasant display from late spring, well into summer. Plants are valued for their attractive foliage as well as their flowers and do best in half shade, in moist but well drained soil. Full sun is only recommended if sufficiently moist. Whether in sun or shade, good drainage is vital. Polemonium is suitable for perennial borders, but really shines in the partially shaded, woodland garden.  Zone 4. 08-FullSun-s 07-PartialShade-s 04-Drip2 03-Drip3 scissors

    reptans ‘Stairway to Heaven’     A very hardy large-leafed Polemonium with broad, bold, cream variegated foliage, tinged pink. 12in. stems bear true blue flowers May-June. High tolerance to New England's heat and humidity. zone 3.

    yezoense ‘Bressingham Purple’    (Purple Leaf Jacob's Ladder) Foliage emerges a rich purple color in spring and gradually changes to deep green as temperatures increase. Deep lavender flowers are borne on erect burgundy stems that rise 1' above a base of pinnately compound, deep, forest green leaves. Blooms May-June, making a pleasing, no-fuss, early season display of flowers followed by foliage that remains attractive all season. For sun to part shade with organic, reasonably moist soil. Deer resistant. Zone 3.

Polygonatum See woodland plants.

Porteranthus tri 175

Porteranthus (Gillenia) trifoliata     (Bowman's Root)  Large numbers of one-inch star-shaped white flowers on wiry red branches . Blooms freely late May through June. Plants have an habit with a shrub-like appearance. When in bloom, the glistening white flowers resemble white moths flitting through the branches. This under-used plant not only adds shape and texture, but it also thrives in dry, shady sites. Eastern U.S. native. Zones 4-8. 2-3 ft. Part shade, garden soil.

Porteranthus (Gillenia) trifoliatus ‘Pink Profusion’      (Pink Bowman’s Root) A distinctive shade perennial with lots of delicate, pink flowers produced all throughout shrub-like stens, late May-June. The effect is striking with flowers appearing to gently flit about within the confines of the 4', vase-shaped clumps.  Does well in dry, shady sites. Eastern U.S. native. Zones 4-8.

Potentilla atrosanguinea ‘Scarlet Starlet’ New    Similar to P. atrosanguinea ‘Red’ except with brighter red flowers above attractive silvery/green foliage. 1-1' high, clump forming, with an upright habit that's more dense than other selections. Best in average, even infertile, full sun locations. An easy to grow, all-around fine border plant that adds exciting color to the early summer garden. Looks fantastic combined with Artemisia ‘Powis Castle’. Deer resistant. Full sun. Zone 4.

Primula Amethyst Ice (Belarina® Series) New    A beautiful new primrose with large, double, violet blue flowers, each petal outlined with a striking thin white margin. 5-8" tall. Extends the primrose season by blooming in mid-spring, somewhat later than others in the Belarina Series. Hardy and vigorous, preferring part to full shade and evenly moist soil. Suitable for boggy and pond side locations, but does just fine in rich, evenly moist garden soil. 

Primula Belarina Cobalt Blue

Primula Belarina® Series Colbalt Blue       Large, double, rich blue flowers bloom in early spring with a spellbinding depth of color. The lush indigo blooms are a feast for the eye as they bloom profusely in tight clusters at 5"-8" high over mounds of bright green foliage, and, while possessing a fragile beauty, plants are tough, reliable garden performers. Flowers are sterile so bloom is especially long, extending from early through late spring. Zone 4.

Primula capitata Salvana 175 #1

Primula capitata ssp. mooreana (Salvana)     Small, fluted, dark violet, silver-powdered, flowers are held 10ins. above the rosetted foliage in large, flattened clusters, each flower positioned horizontally in tight discs, two or three levels deep. The rich purple color is deepest toward the outside with centers heavily silver powdered. Sensational! Unlike any Primula we’d seen before.

Primula denticulata 'Alba'

Primula den. 'Alba'    (Drumstick Primrose)  Golf ball-sized, white globes in April and May on 2-8" stems. Easily grown and frost resistant, asking only moist soil with good drainage and partial shade. One of the earliest Primulas to flower. Zones 3.

    denticulata 'Blue Selection'    (Drumstick Primrose)  Large, golf ball-sized, lavender/blue globes in April and May on 2-8" stems. Easily grown and frost resistant, needing only moist soil with good drainage and partial shade. One of the earliest Primulas to flower and always a welcome sight for winter-weary gardeners. Zones 3.

    denticulata 'Rubin'     As above, with carmine-red flowers.

Primula elator Gold Lace 175

elatior ‘Victorian Laced Primroses’ New    A mix of distinctive hybrids, all with a wide golden-yellow eye and petals ranging from brown to crimson with golden or silver edges. Height is around 10”, early spring blooming. For part shade with rich, evenly moist, well-drained soil. Deer resistant. Zone 5. .

    japonica ‘Alba’    Stately, 18” tall candelabras of white flowers in June-July. For part to full shade with consistent moisture, even in sun with adequate moisture. Always most effective in groups and drifts. Attracts butterflies and hummingbirds. Nice for cutting.  Zone 4.

    japonica ‘Millers Crimson’    18in. stems ringed with 7 to 10 tiers of brilliant crimson, tubular flowers in whirls encircling the stems. Striking in bloom with their brightly colored, architectural flower stalks. Particularly effective massed in the moist, partially shaded garden. Zone 4.

    sieboldii    10-12" airy flower cluster bloom in various shades of pink. Quick to develop tight mats of light, pastel green rosettes that form the perfect backdrop to the delightful, rosy pink flowers. Blooms profusely in early to mid spring and then obligingly goes dormant. Be sure to mark its spot well to make sure they’re not accidentally dug up. Zone 4.

    veris   Common throughout the English countryside along byways and in hedgerows, heralding the arrival of spring. Also right at home in American gardens, blooming for many weeks in early spring. Self-seeds nicely to form slowly expanding colonies that combine effectively with the purple flowers of Phlox divaricata and Phlox stolonifera. Tolerates sunnier and drier locations than many other Primula. Zone 5.

Primula v Sunset Shades

Primula veris ‘Sunset Shades’    Similar to the species except with a mix of orange to deep red flowers, with warm yellow throats that contrast nicely with the hot petal colors. Grows 8” tall. Easy to grow and reliably perennial, returning each year in late April to add a cheery spot of color to the part shade garden. Very hardy. Through zone 4 and even into zone 3.

 

Pulmonaria (Lungwort)     Pulmonarias are valued as much for their handsome foliage as for the intriguing flowers, most of which open blue from pink buds and then fade back to pink. Plants look their best in part to full shade in average or better soil that's evenly moist and well-drained with mature plants developing increased drought tolerance. In the event that powdery mildew or drought disfigures the leaves, they can be cut back to the ground, and a fresh new crop of leaves will appear in short order. Siting in morning sun may discourage mildew. Good winter drainage is essential to survival. Otherwise, Pulmonaria is a pretty tough little plant, hardy and long-lived, and, not palatable to deer or slugs. All are hardy to at least zone 4.

Pulmonaria Silver Bouquet

Pulmonaria ‘Silver Bouquet     Flowers open coral pink and fade to violet in early spring over silver foliage with a hint of green spotting. An improved P. 'Excalibur' with excellent mildew resistance and better heat and humidity tolerance. Foliage looks good all summer. Part to full shade. Deer resistant. Zone 4.

    ‘Trevi Fountain’     One of the best varieties for flowers. Large cobalt-blue flowers turn to a medium pink as they age. The attractive, long, narrow, silver-spotted foliage holds up well in heat and humidity. If foliage becomes tired-looking in mid summer, a quick shearing will promote fresh new leaves. For part shade or sun if soil is evenly moist. Blooms in early spring for many weeks, bringing early, bold color to the otherwise subdued tones of spring. When flowering is over, the attractive foliage kicks in to provide garden interest for the remainder of the season. Deer resistant. Zone 4.

Pulsatilla vulgaris (Pasque Flower)    Large, mostly horizontal to upfacing, urn-shaped flowers in early spring, followed by attractive, feathery seed pods. Finely dissected foliage is covered with soft silky hairs. Native to Europe and north to Sweden where it grows in full sun, on dry, alkaline soil. Good drainage is critical. Blooms early spring, soon after frost leaves the ground.  Beautiful in flower and post-flower for its attractive seedheads, and, if conditions are righ, quite long blooming. Zone 5. We offer the following selection:

    vulgaris ‘Red Bells’ New 2018    Deep red flowers.

Pulsatilla v Violet Bells

Pulsatilla vulgaris ‘Violet Bells’ New 2018    

Pycnanthemum muticum     A member of the mint family, this 3’ tall aromatic herb has showy silver bracts at the ends of its stems all summer. Lends bulk and vertical dimension to the sunny border, very fragrant. Excellent for cutting. Easy to grow and trouble free in average, well-drained soil, full sun. Zone 3.

Pycnanthemum flexuosum

flexuosum New 2018      (Appalachian Mt. Mint) Clusters of white globular flowers held atop sturdy, upright stems, 2-3’ tall. Willowy foliage gives off a strong minty fragrance that gardeners love and deer hate! All Pycnanthemum are vigorous spreaders whose increase needs to be controlled. This is not a delicate procedure. Simply dig out the overreaching portions and replenish the soil. Job done. Worth the small effort for the pleasure of having the narrow, wispy, fragrant foliage that makes a beautiful “filler” in the border. In addition, clusters of white flowers bloom late season, and, it’s one of the very best pollinator plants, attracting butterflies, hummingbirds, moths and dragonflies, and just about every other pollinator on the hunt for nectar. Not fussy about soil and displays a more restrained habit than other Mountain Mints. Zone 5.
