Growing conditions

It tolerates full shade. USDA rates it as having moderate water needs. Its drought tolerance is rated low. It will not tolerate waterlogged soil — USDA rates its anaerobic tolerance as none. It is recorded on soils from pH 5 to 7.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 6.

Size and growth

At maturity it reaches about 30 ft, making it a substantial woody plant. 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. Its fruit or seed heads are conspicuous, extending interest past flowering. Its active growth period is spring. USDA rates its lifespan as short, so plan on replacing or resowing it rather than treating it as permanent structure.

What the site needs to provide

USDA records it across sites receiving 40 to 60 inches of annual precipitation. It needs at least 160 frost-free days to finish its season. It roots to at least 12 inches. Fertility requirement: high.

Propagating it

Propagate it from seed, bare root and container stock. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. Its seed spreads at a slow 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 low, and it can resprout after damage. Its growth form is recorded as single 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.
