Growing conditions

It grows in partial shade. USDA rates it as having needs consistently moist ground. Its drought tolerance is rated none — it needs reliable moisture. It will not tolerate waterlogged soil — USDA rates its anaerobic tolerance as none. It is recorded on soils from pH 5.5 to 7.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 6.

Size and growth

At maturity it reaches about 1 ft, making it a low, mat-forming plant. It grows slowly.

Bloom period

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

A flowering date, not a pollinator rating.

Foliage, flower and season

Summer foliage is green, fine 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 40 to 60 inches of annual precipitation. It needs at least 200 frost-free days to finish its season. It roots to at least 6 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 medium, and it can resprout after damage. Its growth form is recorded as rhizomatous.

Role in a guild

Ground cover. In a layered planting this is the lowest layer — it shades soil, holds moisture, and suppresses weeds. The layer is derived by a fixed rule from growth habit and mature height.
