Growing conditions
It grows in partial shade. USDA rates it as having moderate water needs. Its drought tolerance is rated none — it needs reliable moisture. It is recorded on soils from pH 6 to 8.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 7.
Size and growth
At maturity it reaches about 20 ft, making it a small tree or large shrub. It grows quickly.
Bloom period
USDA records a bloom period of June. Flowers are white.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is yellow-green, medium in texture. Its flowers are not conspicuous — a plant for form and foliage. Its active growth period is spring and summer. USDA rates its lifespan as moderate.
What the site needs to provide
USDA records it across sites receiving 40 to 60 inches of annual precipitation. It needs at least 185 frost-free days to finish its season. It roots to at least 24 inches. Fertility requirement: medium.
Propagating it
Propagate it from cuttings, bare root and container stock. Seed needs cold stratification — a period of moist chilling — before it will germinate, so sow in autumn or chill it artificially before a spring sowing. Its seed spreads at a moderate rate. It spreads vegetatively at a rapid rate.
Resilience and wildlife
Browsing animals find it moderately palatable, so expect deer and rabbits to take an interest. Its fire tolerance is rated high, and it can resprout after damage. Its growth form is recorded as rhizomatous.
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 SASE3, 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.
