Ground covers, Perennials
Closely related to Epimedium and likewise used as groundcovers in shady spots. Wiry leafstalks grow directly from creeping underground stems; leaves have numerous broad leaflets that resemble small ivy (Hedera) leaves. Thread-like flower stalks rise above foliage in late spring or early summer, bearing drooping clusters of small blossoms. Petals and sepals are sharply reflexed, giving flowers a windswept look. Plants spread slowly from an ever-enlarging mat of roots, forming sizable patches in time. Set plants about 1 1/2 ft. apart. Need cool, moist, acid conditions.Vancouveria chrysantha
