Growing conditions
It tolerates full shade. USDA rates it as having moderate water needs. Its drought tolerance is rated low. 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 3.
Size and growth
At maturity it reaches about 16 ft, making it a small tree or large shrub. It grows quickly.
Bloom period
USDA records a bloom period of August through September. Flowers are red.
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 spring. Its winter foliage is dense, which makes it useful for year-round screening. USDA rates its lifespan as long.
What the site needs to provide
USDA records it across sites receiving 22 to 60 inches of annual precipitation. It needs at least 140 frost-free days to finish its season. It roots to at least 10 inches. Fertility requirement: medium.
Propagating it
Propagate it from seed, 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 slow rate. It spreads vegetatively at a slow 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
Climber. In a layered planting this is it uses other plants or structures for vertical support rather than standing on its own. The layer is derived by a fixed rule from growth habit and mature height.
