Growing conditions

It grows in partial shade. USDA rates it as having low water needs once established. Its drought tolerance is rated low. It will not tolerate waterlogged soil — USDA rates its anaerobic tolerance as none. It is recorded on soils from pH 5 to 7.3 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 7.

Size and growth

At maturity it reaches about 6 ft, making it a plant that will finish above head height. It grows slowly.

Bloom period

USDA records a bloom period of March through April. 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 and summer. USDA rates its lifespan as moderate.

What the site needs to provide

USDA records it across sites receiving 13 to 35 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 300 frost-free days to finish its season. It roots to at least 7 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 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 none. 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.
