Growing conditions
Its cold limit is zone 11.
Size and growth
At maturity it reaches about 39 ft, making it a substantial woody plant.
Bloom period
USDA records a bloom period of June through August. 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. Its active growth period is spring.
What the site needs to provide
It needs at least 365 frost-free days to finish its season. It roots to at least 36 inches. Fertility requirement: medium.
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 fire tolerance is rated medium. Its growth form is recorded as single crown.
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.
