Distylium hybrids are an exciting new arrival in the nursery trade. They are a Southern gardener’s dream plant because they are evergreen, compact, disease and insect resistant, and are heat and drought tolerant. Distylium hybrids will also grow in wet soils. One clear advantage is that the plants require very little pruning. In addition to this, they produce a small reddish maroon flower from late January until March. The seed is a small brown capsule the same color as the stem and it is not invasive.

Distylium hybrids were developed by Dr. Michael Dirr, a retired University of Georgia horticulture professor, along with his plant professional partners, Jeff Beasley and Mark Griffin at Plant Introductions Inc. Currently, there are five available introductions that originate from the cross between two Isu-trees Distylium racemosum and D. myricoides. Distyliums are native to China and Japan. They are a member of the witch hazel family Hamamelidaceae, and a distant cousin to the common witch hazel, Hamamelis virginiana, which is native to the Eastern United States.

Due to their toughness, Distylium hybrids are an excellent alternative to laurels, junipers, hollies, Indian hawthorns, boxwoods, and in Dr. Dirr’s words “other green meatballs”.

Mature Height & Spread

Depending on the variety, the cascading growth habit ranges from three to ten feet in height and four to eight feet wide with alternate leaves that are a glossy dark green to blue green. Some of the varieties have coppery-red new foliage.

Cultivation

Light tip pruning in June spurs new growth and a denser growth habit. This is best done before the flower buds are set in late summer. A late winter tip pruning may also be done after the plant has bloomed, but the best advice is minimal attention. They will grow from light shade to full sun. When planted in shaded areas, Distyliums will have a looser shape.

Problems

There is no significant pest or disease damage to be noted. Furthermore, the plants have a high resistance to deer and rabbits munching on them.
