Growing Distylium

Latin Name Pronunciation: dis-sty' lee-um  

Distylium is a small genus of flowering, broadleaf evergreen shrubs in the Witch Hazel family (Hamamelidaceae from China, India, Japan, Korea, and Malaysia. Its dense, compact form, fine-textured leaves, winter blooms, low maintenance needs, unfussiness about soil, and unattractiveness to deer and rabbits recommend it for many garden uses, including as a substitute for Boxwood.

Modern cold-hardy cultivars extend the range to Zones 6 or 7 if plants are situated in a protected location. Plant as a hedge or specimen in a spot that is shielded from hot, afternoon sun in hot areas. At the northern end of the range, plant where it will be protected from strong, winter sunlight and cold winds; mulch well to protect roots from frigid weather and freeze/thaw cycles.

Light: Sun to part shade; will grow in deeper shade but become leggy and produce fewer blooms. Site with afternoon shade to protect from leaf scorch in warmest zones, and provide winter shade in cold areas.

Soil: Average to fertile soil. Distylium is tolerant of sandy soils and clay, but soil must be well-drained. Mulch to preserve soil moisture and insulate roots.

Watering: Low to moderate water needs, drought-tolerant once established. Will not tolerate waterlogged soil.

Fertilizing: Apply a slow-release balanced fertilizer sparingly in spring. In fertile soil, fertilizer may not be needed; occasional compost is beneficial.

Pruning: The compact habit of these shrubs requires little or no need for pruning, other than correcting for any broken branches. Snip tips lightly after flowers have faded in early spring, if desired, to promote denser growth or correct form.

Pests/Diseases: Susceptible to Phytophthora root rot in wet, poorly drained soils.
