Growing conditions

It grows in partial shade. USDA rates it as having low water needs once established. Its drought tolerance is rated high. It will not tolerate waterlogged soil — USDA rates its anaerobic tolerance as none. It is recorded on soils from pH 5.2 to 7.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 3.

Size and growth

At maturity it reaches about 5 ft, making it roughly waist to chest height. It grows at a moderate rate.

Bloom period

USDA records a bloom period of May through June. 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 fruit or seed heads are conspicuous, extending interest past flowering. Its active growth period is spring and summer. USDA rates its lifespan as long.

What the site needs to provide

USDA records it across sites receiving 12 to 40 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 100 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 slow rate. It spreads vegetatively at a moderate 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 rhizomatous.

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.
