Growing conditions

It needs full sun. USDA rates it as having needs consistently moist ground. Its drought tolerance is rated none — it needs reliable moisture. It tolerates saturated, poorly drained ground well (USDA rates its anaerobic tolerance high). It is recorded on soils from pH 4 to 7.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 5.

Size and growth

At maturity it reaches about 6.6 ft, making it a plant that will finish above head height. It grows quickly.

Bloom period

USDA records a bloom period of June through August. Flowers are white.

A flowering date, not a pollinator rating.

Foliage, flower and season

Summer foliage is gray-green, coarse in texture. Its flowers are conspicuous. Its active growth period is spring. USDA rates its lifespan as moderate.

What the site needs to provide

USDA records it across sites receiving 35 to 65 inches of annual precipitation. It needs at least 160 frost-free days to finish its season. It roots to at least 10 inches. Fertility requirement: medium.

Propagating it

Propagate it from seed and container stock. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. Its seed spreads at a slow rate. It does not spread vegetatively, so it will stay where you put it.

Resilience and wildlife

Browsing animals rate it barely palatable — the sourced basis for calling it deer-resistant. Its fire tolerance is rated low. Its growth form is recorded as multiple stem.

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.
