Growing conditions

It grows in partial shade. USDA rates it as having moderate water needs. Its drought tolerance is rated medium. It is recorded on soils from pH 5.5 to 7 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 10.

Size and growth

At maturity it reaches about 25 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, medium in texture. Its flowers are not conspicuous — a plant for form and foliage. Its fruit or seed heads are conspicuous, extending interest past flowering. Its active growth period is year round. USDA rates its lifespan as long.

What the site needs to provide

USDA records it across sites receiving 40 to 150 inches of annual precipitation. It needs at least 365 frost-free days to finish its season. It roots to at least 36 inches. Fertility requirement: medium.

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 moderate rate. It does not spread vegetatively, so it will stay where you put it.

Resilience and wildlife

Browsing animals rate it barely palatable — the sourced basis for calling it deer-resistant. Its fire tolerance is rated medium, 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.

Where this data comes from

Every value on this page comes from the USDA PLANTS database record for symbol PSGU, or is computed from those values by a fixed rule. Nothing here is estimated or model-generated. Where USDA publishes no value, this page omits the claim rather than filling the gap.
