Growing conditions

It tolerates full shade. USDA rates it as having low water needs once established. 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 4.5 to 8 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 4.

Size and growth

At maturity it reaches about 16 ft, making it a small tree or large shrub. It grows quickly.

Bloom period

A flowering date, not a pollinator rating.

Foliage, flower and season

Summer foliage is green, medium 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 moderate.

What the site needs to provide

USDA records it across sites receiving 38 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: medium.

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

Climber. In a layered planting this is it uses other plants or structures for vertical support rather than standing on its own. The layer is derived by a fixed rule from growth habit and mature height.
