Epimedium alpinum

Epimedium alpinum   (Cc. 920002)

This drought tolerant spreading species from southern Europe sports very small flowers held below and among medium-sized leaflets. Inner-sepals are red behind creamy-yellow petals/spurs. 12" tall. The leaflets flaunt a complementary thin, mascara-like red edge while the plant is in bloom. Spreads 8-12" a year, forming an open groundcover. Semi-evergreen.   $8

Epimedium alpinum 'Shrimp Girl'

E. alpinum  ‘Shrimp Girl’  (Cc. 930006)

The clone ‘Shrimp Girl’ is shorter in height (6-8”) than E. alpinum with shorter rhizomes; spreading only 4-5” a year, but its dense growth habit and thick foliage make it far supe­rior at crowding out weeds. Tiny blooms appear below the leaves and are not usually noticeable unless the plant is elevated on a hillside. A short, neat, ground covering Epimedium with a "cool" name. Semi-evergreen.  $8

Epimedium grandiflorum 'Spring Wedding'

E. grandiflorum   ‘Spring Wedding’  (Cc. 950237)   

2003 Cobblewood Introduction

The fresh spring foliage of this selection emerges dark purple, then lightens and expands to display a bold, 1/4” wide, mahogany-red edge.  Very floriferous, it produces numerous flower stems held well above the foliage. The medium-sized flowers have soft lavender sepals backing white petals with downward curving spurs. A plant handsome in both flower and foliage. 10” tall in bloom. Semi-evergreen leaflets hold well into autumn when they turn a limey shade of green. $18

Epimedium grandiflorum var. violaceum 'Bronze Maiden'

E. grandiflorum var. violaceum  ‘Bronze Maiden’  (Cc. 920016)

***1999 Cobblewood Introduction***

Spring leaflets emerge a glossy mahogany-red, resembling molten chocolate.  This intense color lasts about a month in our climate and complements the medium-sized lavender flowers. 8” in bloom, with a second growth flush to 12”. Semi-evergreen. $15

Epimedium pubigerum Cc. 920029

E. pubigerum     (Cc. 920029)

Attractive small, round, heart-shaped leaflets with a matte surface, a wavy edge and a bronze overlay in spring, form on stems 8 to 10" tall. Full sprays of very small, pink-flushed, creamy-white flowers hover well above the leaves at 16-20". Semi-evergreen.  $12

Epimedium pubigerum Cc. 950215

Epimedium pubigerum   (Cc. 950215)

This clone bears creamy-white flow­ers-- almost like tiny molars, creating a baby's breath effect-- held high above especially rounded, glossy dark green leaflets. Foliage 8-10" tall with flowers stems held at 16-20" tall. Drought tolerant. Semi-evergreen.  Not available in 2018.

Epimedium pubigerum Cc. 000996

E. pubigerum     (Cc. 000996) 

A unique running version of this normally clump-forming and especially drought tolerant species. Handsome corrugate bright green medium-sized leaflets form an attractive, open ground cover. Abundant flower sprays reminiscent of baby's breath cover the foliage extending to 16". Each small flower has cupped white sepals that sport a smear of rose color along their lengthwise edge. A slow spreader with 2-4" rhizomes. Foliage reaches 8". Semi-evergreen Not available in 2018.


Epimedium sempervirens 'Aurora'

E. sempervirens  ‘Aurora’  (Cc. 920018)      

Dwarf form with large, dark silky, silvery lavender blooms and glossy foliage even as a deciduous type. Small/medium-sized leaflets. 6" tall in bloom with a second flush to 9". The new growth displays occasional dark flecking in spring. Second flush may have a pink blush as the photo shows. Often has good orange-red fall color when grown in bright shade or some sun. Named by Dick Weaver and sold by We Du as a cultivar of E. grandiflorum. Semi-evergreen. (Photo of foliage by Jan Sacks, Joe Pye Weed's Garden)  $12 

Epimedium sempervirens 'Candy Hearts'

Epimedium sempervirens  ‘Candy Hearts’

(Cc. 920038)

***2001 Cobblewood Introduction***

Exquisite spring foliage emerges an opalescent rosy-pink tone that slowly recedes over a month’s time to a rose border, before turning solid green. The showy large silvery lavender-pink flowers have wide inner-sepals and look like iridescent pearls against the colorful spring foliage. 9” tall. Semi-evergreen with medium-sized leaflets.   $20

Epimedium sempervirens 'Okuda's White'

Epimedium sempervirens   ‘Okuda’s White’

(Cc. 950036)

Introduced from Japan by George Schenk in the 1970’s. A rare and unusual spreading form of E. sempervirens, with 4-6” long rhizomes. The large, white flowers are typical of the species. The rhizomes have exhibited some winter damage in Massachusetts; so we recommend winter mulch in Zone 5. Grows to 6-8” tall. Forms a nice, short, semi-evergreen groundcover over time.   $12

Epimedium sempervirens 'Rose Dwarf'

E. sempervirens   ‘Rose Dwarf’ (Cc. 950027)

Originally offered by George Schenk in the 1970’s and still quite rare in the trade. We thank Jerry Flintoff for our original stock. Plants 5” tall in bloom with unusually long, narrow, medium-sized leaflets, gradually tapering to a thin point and flecked with bronze in the spring. Flowers similar to those of Violet Queen’, dark violet-lavender with long inner-sepals. Semi-evergreen$12

Epimedium sempervirens 'Secret Arrow'

Epimedium sempervirens ‘Secret Arrow’ (Cc. 950140) 
***2000 Cobblewood Introduction***

Unique, arrow-shaped leaflets distinguish this plant. Large lavender flowers face out¬ward with wide inner-sepals. Cool fall temperatures turn the leaves a beautiful salmon-egg red, with limey green streaks along the main veins $15

Epimedium sempervirens 'Shadow Dancer'

E. sempervirens ‘Shadow Dancer’  (Cc. 000943)   

***2010 Cobblewood Introduction***


This sempervirens selection has turned heads in our nursery for years. It has beautifully banded foliage with a shiny mahogany edge in spring, surrounding a interior flushed with deep red.  The large, bright lavender blossoms have uniform coloring throughout.  15-18” in height. Semi-evergreen.  $22

Epimedium sempervirens "Variegated #1"

Epimedium sempervirens   “Variegated #1”  (Cc. 970190)

From Japan came rumors of a most spectacularly variegated Epimedium heavily dappled with white and pink and costing a small fortune. During Darrell's 1997 trip to Japan with Dan Hinkley he searched specifically for this fabled plant. Once he saw it he just had to have it—the most expensive Epimedium he's ever purchased! It was indeed the nicest variegated Epimedium he'd ever seen...and just as they said, the spring foliage is a swirling collage of creamy white, salmon-pink and apple green. What they didn’t mention was that the white portion of the variegation lasts well into the season.. into August here, before turning mostly green.

White flowers are produced above the semi-evergreen leaves. One of the shorter Epimediums at only 8” tall.    $22

Epimedium sempervirens 'Violet Queen'

Epimedium sempervirens   ‘Violet Queen’  (Cc. 950138)

A spectacular Epimedium. This clone is an exact match for the plant originally named Epimedium violaceum in 1834 which was later changed to a variety of E. grandiflorum... all through the study of dried herbarium specimens. However, this plant is semi-evergreen and nearly identical to other clones Darrell received from west central Honshu including the plant depicted in Don Elick’s book, Japonica Magnifica. Perhaps it is a species of its own. This is the parent that gifted E. x rubrum, E. x versicolor ‘Versicolor’ and ‘Cupreum’ with colorful spring foliage.

Prized for its vibrant, cherry-red new growth and large, rich violet-lavender flowers with very long inner-sepals. Small/medium leaflets have a long, tapered point. Slow to propagate. 12”  Not available in 2018.

Epimedium x 'Domino'

Epimedium x ‘Domino’  (Cc. 990614)  

***2004 Cobblewood  Introduction***

Showy panicles of creamy white and maroon flowers highlighted against handsome mottled foliage in spring. Elegant elongated spring leaflets are sponge-painted in various shades of maroon. Deep reddish-purple outer sepals and dark purple pedicels. Forms a 12 inch mound of spiky evergreen foliage with soft spines, covered in a halo of flower stems to 16”.  May re-bloom and produce a second flush of mottled new growth under favorable conditions.  A terrific specimen Epimedium for the garden. $22

Epimedium x 'Flame Thrower'

Epimedium x ‘Flame Thrower’ (Cc 990619)

***2009 Cobblewood Introduction***

Cheerful cherry red and creamy yellow flowers dance above the foliage of this hybrid from Darrell Probst. The inner sepals have decorative undulations to their shape, resembling flames licking upwards from the top of the flower. This cross between deciduous and evergreen parent plants gives this hybrid both vigorous growth and deep green, spiny leaflets of good substance. Very drought tolerant.   $25

Epimedium x 'Lemon Zest'

Epimedium x ‘Lemon Zest’  (Cc. 990617)

***2005 Cobblewood Introduction***

 From low, dense rosettes of small, shiny, rounded evergreen leaflets flushed bronze in spring, emerge many erect racemes up to 15” high of cheerful, bright lemon-yellow bells.  A slowly spreading hybrid created by Darrell Probst. $18

Epimedium x 'Lilac Cascade'

Epimedium x ‘Lilac Cascade’  (Cc. 950236)

***2001 Cobblewood Introduction***


What an incredible plant! In spring the new foliage emerges in beautiful shades of rose and pink. By bloom time, the leaflets turn almost solid green with a purplish-red border, forming a perfect mound of cascading foliage. Just above the leaves are clusters of rich violet-lavender flowers. Later, a second flush of vibrant hot raspberry-pink foliage emerges and remains colorful for several weeks. 6 to 8” tall in bloom with the second flush to 10”.  From Darrell Probst's cross between E. sempervirens ‘Candy Hearts’ and E. grandiflorum ‘Yubae’. The foliage is like the former— semi-evergreen, medium-sized round hearts.  $22

Epimedium x 'Pink Champagne'

Epimedium x ‘Pink Champagne’ (Cc. 990618)

***2007 Cobblewood Introduction***

Perhaps the most all around beautiful Epimedium of those that Darrell has developed so far! Upright, heavy flowered panicles of pink and raspberry flowers float well above handsome, mottled foliage in spring. Medium pink sepals cap the top of each widely-arched spur. From the yellow spur tips that reveal their treasure of nectar, the color changes from white to a rich, berry pink, as if the cup was dipped in raspberry sorbet. Elongated, evergreen medium-sized arrow-shaped leaflets contrast purple mottling against a green background. A vigorous grower, it puts on an incredible show with rebloom if it is happy in its environment. 12" tall with flower stems reaching 16".  $25

Epimedium x 'Pretty In Pink'

Epimedium x ‘Pretty in Pink’  (Cc. 130001)

This 2012 Plant Delights Nursery introduction by Tony Avent is a vigorous E. grandiflorum hybrid with exceptional foliage. Small clusters of large, showy flowers with pink spurs and a raspberry cup are held just above the leaves during the mid-late Epimedium bloom season.

The new spring growth is patterned with subdued maroon flecks, eventually hardening off as handsome, glossy, medium-sized green leaflets, followed by a flush of blush pink second growth foliage. Tony describes the leaflets as "tardily deciduous"-- what I call "semi-evergreen". One of the best for thick, lustrous summer foliage. To 12".  $22

E. x 'Serendipity'

Epimedium x 'Serendipity'  (Cc. 060300)

***2017 Cobblewood Introduction***

A chance open-pollinated seedling of E. pauciflorum brought to my attention by to Elaine Chittenden of Smith College Botanic Garden, this selection is an excellent white-flowered, spreading Epimedium-- a rare find. Low and vigorous with loads of cheerful, white flowers (touched with light lavender, but they “read” as white) are scattered 8 to 10” above small, chocolate-edged and irregularly speckled leaflets-- quite unlike any E. pauciflorum I know. Similar to E. grandiflorum var. higoense in size and shape, but it spreads with 1-4” long rhizomes. Initially forms a 4-6” high, dense groundcover, perfect for small gardens or small spaces. Sparse second growth flush to 12". Semi-evergreen. Now how is that for a happy chance!  $22

Epimedium x 'Windfire'

Epimedium x ‘Windfire’ (Cc. 002114)

**2007 Cobblewood Introduction***

Wiry, black-red upright flower spikes rise above the foliage carrying large, canary yellow flowers with small, dark red sepals. The thin reflexed spurs give the flower a very elegant silhouette. Slightly spreading with an open habit, by rhizomes that grow 4” a year. Medium-sized semi-evergreen leaflets form a leafy, open base to 12”. Flower spikes to 20”.   $22 

Epimedium x 'Yokihi'

Epimedium ‘Yokihi’ (Cc. 050030)

An outstanding late-blooming Japanese cross between E. davidii and E. grandiflorum ‘Yubae’, this clumping hybrid produces long arching 18” spikes of large spidery flowers. The dramatic flowers have a flared creamy yellow cup and long, slender spurs backed by short, bright reddish pink inner sepals. Medium green angular leaflets are flushed with bronzy red in spring.   $22

E x cantabrigiense "Red Form"

E. ×cantabrigiense “Red Form” (Cc. 950018)

A tough, slightly-spreading natural hybrid of E. alpinum, which the deeply veined leaves most closely resemble, and E. pubigerum, which the floral sprays most resemble. One of many plants for which we are grateful to Jerry Flintoff, as Darrell has not found it elsewhere in the U.S. This clone was very common in many of the British gardens we visited in April 1998. The sepals are dark red rather than the pale salmon of the clone commonly cultivated in the U.S. Numeroua, small flowers bloom well above the leaves on loosely branched 18” stems. More vigorous than the U.S. form, with larger, medium-sized leaflets. Semi-evergreen. $12

Epimedium x rubrum 'Sweetheart'

Epimedium rubrum  ‘Sweetheart’   (Cc. 930007)

***1997 Cobblewood Introduction***

This cultivar easily rivals Hosta as a bold textural garden accent. The first of Darrell Probst's Epimedium introductions, resulting from a 1991 cross he made between E. sempervirens  ‘Candy Hearts’ and E. alpinum. Flowers with dark rose-red sepals bloom above and below the leaves. Leaflets are much larger, darker green and more rounded than is typical. Large, shiny new leaflets bear a thin red rim in spring. Semi-evergreen. 16" tall. A far superior clone, equally as drought tolerant as E. x rubrum.   $12

Epimedium x sasakii Cc 950137

Epimedium sasakii  (Cc. 950137)

In Japan, wherever the habitats of E. sempervirens and E. x setosum overlap, hybrids occur. These highly variable hybrids were given the name E. x sasakii by Japanese botanists. However, the name is still little recognized by western botanists. All of the clones we've grown so far are semi-evergreen. 6” tall in bloom, second flush to 16”. Small, charming dark grayish-lavender flowers. In spring the leaflets are defined by a dark, thin, mascara-like maroon line at the edge of the leaf. Fall color changes to a taupe or sometimes scarlet with green veining.  Not available in 2018.

Epimedium x setosum Cc. 950163

E. setosum    (Cc. 950163)

This is the typical form of this naturally occurring fertile hybrid collected in northern Kyushu, Japan. It is larger overall than others in commerce, growing up to 12” tall, with larger leaf­lets. Small white flowers are pro­duced in sprays above the leaves that may appear bronzed in spring/fall. Semi-evergreen. $8

E x setosum Cc 960059

E. setosum   (Cc. 960059)

A very floriferous clone from the garden of Harold Epstein. Medium-sized leaflets with prominently spined margins on plants literally covered with numerous sprays of white flowers. 8-10” tall. Semi-evergreen foliage sports a reddish fall color. A favorite of the clones we grow, but each possesses individual charm.  $12

Epimedium x versicolor 'Cherry Tart'

Epimedium versicolor   ‘Cherry Tart’  (Cc. 970064)

***1999 Cobblewood Introduction***

A spontaneous seedling originating in the garden of Judy Springer, formerly of Great Falls, VA. Erect stems sport numerous, outfacing flowers. Large, rose pink inner-sepals back flaming, cherry-red spurs with a bright, lemon-rimmed cup. Spreads slowly by 2-4” long rhizomes. Medium-sized leaflets handsomely flushed with reddish-purple in spring with a mustard to purple blush in fall. 12-15”. Semi-evergreen. $15

Epimedium x versicolor 'Neosulphureum'

E. versicolor   ‘Neosulphureum’  (Cc. 920044)

Undeservedly rare in cultivation, this counterpart to the more com­mon ‘Sulphureum’ is shorter and semi-spreading with 2-4” rhizomes that form a tight groundcover. Pale yellow flowers are held on 12” erect, airy sprays. Flower spurs half as long as the inner-sepals. Spring leaflets are nicely bronzed on stems 6-8” and form a darker background against which to view the soft yellow flowers. Semi-evergreen.    $10

Epimedium x versicolor 'Strawberry Blush'

E. versicolor   ‘Strawberry Blush’ (Cc. 990615)

***2004 Cobblewood Introduction***

Wide, antique pink sepals brushed with rose streaks back a cheerful lemon-yellow cup, which deepens to rose purple short, curved spurs. The soft pastel flowers blend beautifully with the pinkish maroon mottled new spring leaflets. Darkest at the edges, the color fades to green at the center of small/medium-sized leaflets, before turning entirely green. Handsome, medium green, glossy summer/fall foliage. Particularly drought tolerant. Semi-evergreen. Flowers/foliage to 10”.   $15


Epimedium x versicolor 'Sulphureum'

Epimedium versicolor   ‘Sulphureum’  (Cc. 840002)

(Synonym: E. pallidum)

One of the very few herbaceous perennials that persist in abandoned gardens after decades of neglect. Superb in mass plantings, it spreads 4-5” a year, forming a thick groundcover of leaves that holds its own against weeds. Long sprays of pale yellow flowers with spurs nearly equal in length to the inner-sepals are produced above leaflets flushed red in spring. 16" tall. Semi-evergreen leaves. $10

Epimedium x versicolor 'Versicolor'

E. versicolor  ‘Versicolor’  (Cc. 890006)

(syn. E. x versicolor 'Discolor')

Quite rare in gardens, this has long been one of our favorite clones. Delicate flowers open a deep, rich salmon, and fade over the course of several days. Large panicles of flowers hover above leaflets strongly flushed with red in spring. Spreads 4 to 5" a year forming a gorgeous mass of riotous color in spring. 14" tall. Semi-evergreen. $12

E x youngianum 'Fairy Dust'

E. youngianum  ‘Fairy Dust’ (Cc. 950241)

***2004 Cobblewood Introduction***


Small, simple, lavender-pink flowers with small white spurs lift their faces above the foliage in spring. The color deepens toward the edge of each flower part. Fresh spring leaves have the texture of silk and are tinted in a delicate shade of mocha. Compact growth at 7” in bloom, and flowers to 10”, creating a neat and tidy effect.  $12

Epimedium x youngianum ‘Grape Fizz’

E. youngianum   ‘Grape Fizz’ (Cc. 950242)

***2004 Cobblewood Introduction***


Small, rich, grape-purple buds open to release full, blue-lavender blossoms with irregular white highlights at the base of each part. Each flower has four vestigial white spurs. Flowers form a loose tumble above a low 5” mound of lime-green foliage. 7” in bloom. Long lasting bloom. New foliage has a brownish tint. The medium-sized leaves have acute basal lobes and deeply indented veins, producing a seer­sucker effect.  $15.

Epimedium x youngianum 'Little Shield'

Epimedium youngianum  ‘Little Shield’ (Cc. 950240)

***2004 Cobblewood Introduction***

Distinctive shield-shaped leaves are part of this plant’s allure. In spring a soft overlay of milky mocha covers the small to medium-sized leaves, heavily indented at the veins. 8” tall in bloom, with numerous, perky 3/4” white flowers held above the foliage. Spurs slightly longer than sepals. Semi-evergreen$12 

Epimedium x youngianum 'Milk Chocolate'

Epimedium youngianum  ‘Milk Chocolate’

(Cc. 990616) 

***2005 Cobblewood Introduction***

 ‘Milky Way’ sometimes produces sporadic new spring leaflets that are nearly solid purple. Darrell once found an entirely purple leaf, selected that division, and began propagating it to stabilize the characteristic. The resulting ‘Milk Chocolate’ produces small chocolate-purple leaves with tiny green flecks in spring. The color remains for weeks in contrast with the multitudes of white, medium-sized flowers. Semi-evergreen. 6” in bloom, to 12”. $15

Epimedium x youngianum 'Milky Way'

E. youngianum  ‘Milky Way’  (Cc. 920046)

This Dick Weaver introduction ­has pristine, medium-sized white flowers with long spurs. The new spring foliage is attractively speckled with a multitude of deep purple markings. At maturity, the small semi-evergreen leaflets display an attractive persistent silver overlay on the main veins. 6" in bloom. Second growth to 12".  $12

Epimedium x youngianum 'Royal Flush'

E. youngianum  ‘Royal Flush’ (Cc. 950239) 

***2004 Cobblewood Introduction***

New leaflets emerge a rich chestnut, changing to a bright bur­gundy mottling between green veins with the deepest color toward the edges. First flush of beautiful, thick foliage rises to 9” and holds its brilliant spring colors longer than most. Medium–sized light lavender flowers have white spur tips. Lighter tones highlight the edge of the cup. Second flush of colorful foliage to 14”. Semi-evergreen.   $15

Epimedium x youngianum 'White Star'

Epimedium youngianum  ‘White Star’

(Cc. 950011)

***2000 Cobblewood Introduction***

A spontaneous seedling found in the Asian Collections at the U.S. National Arboretum. This floriferous clone bears small, white flowers with spurs equal in length to the inner-sepals. The small thick leaflets remain evergreen in USDA Zone 7 and farther south, semi-evergreen elsewhere. Delightful at 5" tall in bloom, eventually growing to 8". $10

Iris koreana

Iris koreana  

During his last stop in S. Korea in 1997, Darrell crawled up a nearly dry stream bed beneath dense scrub for this treasure. It produces glowing yellow 1-1/2” flowers, each with a narrow brown halo surrounding the signal. Flowers are held on 6” stems above the expanding leaves. Semi-evergreen to 12”. Best with 3-4 hours of sun here, it grows in bright shade and perhaps even full sun. Produces a substantial, grassy-leaved clump after several years. Not available in 2018.

Iris koreana 'Firefly Shuffle'

Iris koreana ‘Firefly Shuffle’  

***2010 Cobblewood Introduction***

A very floriferous clone of this Asian species iris, and a good grower. Mid May is heralded with the annual explosion of sunny, bright lemon yellow blossoms covering the plant. Great for the rock garden.  Best in bright shade or a few hours of direct sun, it forms a grassy-leaved clump that slowly spreads into a “patch”. Semi-evergreen.   Sold out for 2018.

Iris odaesanensis

Iris odaesanensis

Pristine white flowers with a yellow signal edged in a thin, brown halo. Two flowers, each nearly 2” in diameter, are borne atop 8” stems in late May. Semi-evergreen leaves expand after bloom to reach 12” long, 1/2” wide, forming dense clumps of arching foliage. Prefers a little more sun than Epimediums. $12

Iris odaesanensis Chuwangsan #3

Iris odaesanensis “Chuwangsan #3”

I. odaesanensis was previously known to exist only on the top of Odae-san (san = mountain). To the surprise of his Korean host from Chollipo Arboretum, Darrell found a few pockets of it growing on a wooded rocky ledge on Chuwangsan, 100 miles south of Odaesan. He collected three unique clones.

The flowers of this vigorous grower lack the typical brown halo surrounding the signal. It also seems to be less tasty to the local slugs. Semi-evergreen.  $12

Iris odaesanensis 'Ice Whisper'

Iris odaesanensis  ‘Ice Whisper’ 

***2014 Cobblewood Introduction***

A beautiful icy blue-lavender flowered variant of this normally white-flowered species iris. Darrell collected a pale lavender-flowered clone in the wild in Korea, and grew seed from that plant. This is his deeper lavender flowered selection from that seedling batch.  $22

Primula kisoana forma alba

Primula kisoana f. alba 

 The white-flowered form of this spreading Japanese woodland primrose. Downy, scalloped light green foliage is very different from other Primulas. Great as a low ground cover planted at the base taller woodland plants.  Clusters of white flowers in mid-May. Prefers evenly moist, humus-rich soils.  4-6” high. Forms extensive, thick colonies over time.  $15

Trillium pusillum 'Roadrunner'

Trillium pusillum  ‘Roadrunner’

***2007 Joe Pye Weed's Garden Introduction***

Trilliums are notoriously slow to propagate. While this diminuitive species propagates faster than most, this clone grows particularly rapidly, making a substantial, floriferous clump in just a few years. New spring leaves emerge dark purple, almost black, and remain so as the 1-1/2” white, tri-petaled flowers open. Each petal has a rosy reverse. Foliage matures to green as the flowers blush to pink as they age.  Never fails to draw attention during our open nursery weekends. $15
