Growing conditions
It needs full sun. USDA rates it as having needs consistently moist ground. Its drought tolerance is rated low. It handles periodically wet ground (USDA rates its anaerobic tolerance medium). It is recorded on soils from pH 6.5 to 7.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 7.
Size and growth
At maturity it reaches about 12 ft, making it a small tree or large shrub. It grows at a moderate rate.
Bloom period
USDA records a bloom period of August through September. 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 active growth period is spring, summer, fall. USDA rates its lifespan as moderate.
What the site needs to provide
USDA records it across sites receiving 9 to 24 inches of annual precipitation. The low end of that band is genuinely arid, so it has a wide tolerance for dry country. It needs at least 250 frost-free days to finish its season. It roots to at least 12 inches. Fertility requirement: low — no feeding needed on ordinary garden soil.
Propagating it
It takes readily from seed, 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 medium, and it can resprout after damage. Its growth form is recorded as multiple stem.
Role in a guild
Shrub layer. In a layered planting this is woody mid-level structure between the understory and the ground. The layer is derived by a fixed rule from growth habit and mature height.
