Growing conditions

It grows in partial shade. Its drought tolerance is rated medium. It is recorded on soils from pH 5 to 8 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 11.

Size and growth

At maturity it reaches about 25 ft, making it a substantial woody plant. It grows slowly.

Bloom period

USDA records a bloom period of June through August. Flowers are white.

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 year round. Its winter foliage is dense, which makes it useful for year-round screening. 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

It needs at least 365 frost-free days to finish its season. It roots to at least 24 inches. Fertility requirement: low — no feeding needed on ordinary garden soil.

Propagating it

Seed is the only propagation method USDA lists. Division and cuttings are not listed as options. USDA records no cold-stratification requirement, so seed should germinate without a chilling period.

Resilience and wildlife

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.
