Plant Details

Hardy, little-known members of witch hazel family with lovely layered, arching branches and small clusters of late-winter to early-spring flowers in leaf axils followed by small, nutlet-like fruit. Maintains green color throughout winter. Adaptable but grows best in well-drained soil rich in organic matter. Responds well to hard pruning.

D. hybrids. Several excellent hybrids have been developed from the species listed below. All have reddish maroon flowers in late winter. 'Blue Cascade' has bronzy red new growth maturing to blue-green; cascading to 3 ft. high by 4 ft. wide. 'Emerald Heights' produces bright green new growth darkening to dark blackish green; grows 5-6 ft. high and wide. 'Vintage Jade' is spreading and wonderfully layered to 2 ft. high and 5 ft. wide in 5 years; shiny, dark green foliage.

D. myricoides. BLUE ISU TREE. From China. Spreading, arching shrub with narrow, blue-green leaves 33 in. long and 1 in. wide. Grows 45 ft. high by 8 ft. wide. Pretty, but not especially showy, clusters of red flowers. Cut branches good for arrangements.

D. racemosum. ISU TREE. From Japan. Spreading, eventually becoming an upright shrub to 15 ft. high. Reddish purple flowers in early spring; fairly showy. Oval, shiny, dark green leaves; 1 in. long. Best in moist, acid soils.
