Growing conditions
It grows in partial shade. Its drought tolerance is rated low. It handles periodically wet ground (USDA rates its anaerobic tolerance medium). It is recorded on soils from pH 6 to 8 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 8.
Size and growth
At maturity it reaches about 15 ft, making it a small tree or large shrub. It grows at a moderate rate.
Bloom period
USDA records a bloom period of March through May. Flowers are white.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is green, coarse in texture. Its flowers are conspicuous. It carries conspicuous autumn colour. Its active growth period is spring.
What the site needs to provide
USDA records it across sites receiving 33 to 68 inches of annual precipitation. It needs at least 247 frost-free days to finish its season. It roots to at least 36 inches. Fertility requirement: low — no feeding needed on ordinary garden soil.
Propagating it
Cuttings is the only propagation method USDA lists.
Resilience and wildlife
Its growth form is recorded as single stem.
Role in a guild
Shrub layer. In a layered planting this is woody mid-level structure between the understory and the ground. The layer is derived by a fixed rule from growth habit and mature height.
