Epimedium grandiflorum ‘Red Queen’

E. grandiflorum ‘Red Queen’ (Cc. 950055)

Harold Epstein bought this imposing plant in Japan many years ago, and nicknamed it “Red Queen”. As far as we can determine, it was not a named cultivar. Large, vivid, rose-red flowers peek out from under huge leaflets that may grow to 6” long/4” wide. The bold fall foliage of this regal Epimedium sometimes turns shades of pink/orange. A second growth flush of red-tinted foliage reaches to 14”. A vigorous, bold-textured choice that makes a substantial clump over time.

Epimedium grandiflorum f. flavescens #2

E. grandiflorum f. flavescens #2 (Cc. 940550)

Of the over 50 distinct clones of E. grandiflorum f. flavescens that Darrell brought back from Japan, this is by far the earliest to bloom with large, pale greenish-yellow flowers held below large, elliptical, bright apple green leaflets. Large, mature leaflets etched by the nearly parallel main veins make a bold, elegant garden statement. From the Kyoto Botanic Garden in Japan, it is very different from other clones circulating in the U.S. 20" tall. Clear yellow fall foliage. Spreads by 2-4" rhizomes.

Epimedium x rubrum ‘Sweetheart’

Epimedium x 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. Foliage is far superior to E. x rubrum, and the plant is much more drought-tolerant. Spreads by 2-4" rhizomes.

Epimedium grandiflorum f. flavescens #3

Epimedium grandiflorum f. flavescens #3 (Cc. 950129)

Originally sold by Siskiyou Rare Plant Nursery under the invalid name E. macranthum ‘Aureum’. At 14”, it is shorter than most other E. grandiflorum f. flavescens clones offered here. Beautiful red-copper young leaflets unfurl over large, pale yellow flowers. After bloom, large, bold, oval-shaped leaflets expand to form an impressive mound. Clear yellow fall foliage color. Spreads by 2-4" rhizomes.

Epimedium ‘Pink Champagne’

Epimedium ‘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 occasional re-bloom if it is happy in its environment. 12" tall with flower stems reaching 16".

Epimedium koreanum ‘Harold Epstein’

Epimedium koreanum ‘Harold Epstein’ (Cc. 930004)

A very cold hardy clone with huge flowers for an Epimedium— gorgeous and butter yellow. Named in honor of Harold Epstein by plantsman Jerry Flintoff, its enormous leaflets can reach over 6” long and 4-1/2" wide. Spreads 6-12" a year. It usually takes 2-3 years to establish itself and become most impressive. The flowers emerge before the leaflets unfurl in early spring. E. koreanum is notorious for just putting up one set of leaves per node each season. If the leaf suffers damage, the rhizome will remain dormant until the following year. ‘Harold’ is a great bold-textured vigorous ground cover for large areas where it can spread unimpeded. It is especially useful in combination with early spring bulbs for sequential bloom. After bloom the expanding leaves serve as camouflage for the dying bulb foliage. 15" tall.
