Growing conditions
It grows in partial shade. USDA rates it as having moderate water needs. Its drought tolerance is rated high. It is recorded on soils from pH 5 to 7 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 5.
Size and growth
At maturity it reaches about 2.2 ft, making it about knee height. It grows at a moderate rate.
Bloom period
USDA records a bloom period of May through June. Flowers are purple.
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 32 to 45 inches of annual precipitation. It needs at least 130 frost-free days to finish its season. It roots to at least 10 inches. Fertility requirement: medium.
Propagating it
Propagate it from container stock and sprigs. 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. Its growth form is recorded as rhizomatous.
Role in a guild
Herb layer. In a layered planting this is the herbaceous middle — perennials and grasses that fill the space between ground cover and shrubs. 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 SAOF4, 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.
