Growing conditions
It needs full sun. USDA rates it as having low water needs once established. Its drought tolerance is rated medium. It is recorded on soils from pH 6.5 to 8 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 3.
Size and growth
At maturity it reaches about 18 ft, making it a small tree or large shrub. It grows quickly.
Bloom period
USDA records a bloom period of March through May. Flowers are yellow.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is white-gray, coarse in texture. Its flowers are conspicuous. It carries conspicuous autumn colour. Its fruit or seed heads are conspicuous, extending interest past flowering. 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 26 to 50 inches of annual precipitation. It needs at least 100 frost-free days to finish its season. It roots to at least 18 inches. Fertility requirement: low — no feeding needed on ordinary garden soil.
Propagating it
Propagate it from seed, bare root and container stock. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. Its seed spreads at a moderate rate. It spreads vegetatively at a rapid rate.
Resilience and wildlife
Browsing animals rate it barely palatable — the sourced basis for calling it deer-resistant. Its fire tolerance is rated high, 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.

Where this data comes from
Every value on this page comes from the USDA PLANTS database record for symbol HIRH80, 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.
