Culture
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.
Noteworthy Characteristics
Hamamelis × 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).
The hybrid name intermedia is in reference to the hybrid characteristics being intermediate between the characteristics of the two parent species.
‘Birgit’ is a red-flowered form with upright-spreading branching. It will typically grow to 8-12’ tall and to 12-15' wide. It is noted for its winter-blooming, purplish red flowers -- perhaps the darkest red of the cultivars available today. Each flower has four, narrow, ribbon-like, curled and slightly crinkled petals. Axillary clusters of these flowers bloom along the stems from late January to March. Flowers are mildly fragrant. Ovate-orbicular dark green leaves (to 4” long) turn yellow-orange-red in fall.
Problems
Caterpillars and Japanese beetles may chew on the leaves. Watch for gall aphids, scale, leafroller and leafminer. Potential diseases include powdery mildew, occasional leaf spots and rots. Insect and disease issues are typically not serious and rarely warrant chemical control.
Uses
Superior winter-flowering shrub for the landscape. Shrub borders, woodland gardens. Screen or tall hedge. Good specimen.
