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.
