Growing conditions

It grows in partial shade. USDA rates it as having needs consistently moist ground. Its drought tolerance is rated medium. It handles periodically wet ground (USDA rates its anaerobic tolerance medium). It is recorded on soils from pH 4.5 to 8.8 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 7.

Size and growth

At maturity it reaches about 33 ft, making it a substantial woody plant. It grows quickly.

Bloom period

USDA records a bloom period of March through April. Flowers are green.

A flowering date, not a pollinator rating.

Foliage, flower and season

Summer foliage is green, coarse in texture. Its flowers are not conspicuous — a plant for form and foliage. It carries conspicuous autumn colour. Its active growth period is spring. USDA rates its lifespan as long.

What the site needs to provide

USDA records it across sites receiving 30 to 60 inches of annual precipitation. It needs at least 130 frost-free days to finish its season. It roots to at least 20 inches. Fertility requirement: low — no feeding needed on ordinary garden soil.

Propagating it

It takes readily from seed, cuttings, bare root and container stock. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. Its seed spreads at a rapid rate. It does not spread vegetatively, so it will stay where you put it.

Resilience and wildlife

Browsing animals find it moderately palatable, so expect deer and rabbits to take an interest. Its fire tolerance is rated medium, and it can resprout after damage. Its growth form is recorded as multiple stem.

Role in a guild

Understory. In a layered planting this is the layer beneath the canopy, tall enough to hold structure but shaded from above. The layer is derived by a fixed rule from growth habit and mature height.
