Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Best flowering is in full sun. Prefers moist, acidic, organically rich soils. Consistent moisture is best (leaf scorch may occur during periods of summer drought). Shrubs have some tolerance for clay soils as long as drainage is good. Promptly remove root suckers to prevent colonial spread. It is particularly important to remove root suckers rising from below a graft union. Prune in spring after flowering to control shape and size.
Hamamelis x intermedia hybrids are crosses between Japanese witch hazel (H. japonica) and Chinese witch hazel (H. mollis). They are somewhat coarse, loosely-branched, medium to large, deciduous shrubs that typically grow 12-20’ tall. They are particularly noted for their spidery, often fragrant, mid- to late winter flowers which appear before the spring foliage emerges.
Genus name comes from the Greek words hama meaning at same time and melon meaning apple or fruit in reference to the occurrence of both fruit and flowers at the same time on this shrub (particularly in the case of fall flowering members of the genus).
Hybrid name means intermediate in color, form or habit.
‘Diane’ is a red-flowered form with spreading branches. It typically grows to 8-12’ tall and to 10-15’ wide over 10 years. It is noted for its winter-blooming, mildly fragrant, red to copper-red flowers (to 1” long), each having four, narrow, ribbon-like, crinkly petals. Axillary clusters of these flowers bloom along the stems from late January to March. Broad-oval green leaves (to 6” long) turn attractive shades of yellow, orange and red in fall.
No serious insect or disease problems. Caterpillars and Japanese beetles may chew on the leaves. Watch for gall aphids, weevils, scale, leafroller and leafminer. Potential diseases include powdery mildew, occasional leaf spots and rots.
Superior winter-flowering shrub for the landscape. Shrub borders, woodland gardens. Screen or tall hedge. Good specimen.
