Growing conditions
It tolerates full shade. 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 6 — acidic ground. Its cold limit is zone 7.
Size and growth
At maturity it reaches about 4.5 ft, making it roughly waist to chest height. It grows quickly.
Bloom period
USDA records a bloom period of July. Flowers are white.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is green, medium in texture. Its flowers are not conspicuous — a plant for form and foliage. Its active growth period is summer. USDA rates its lifespan as short, so plan on replacing or resowing it rather than treating it as permanent structure.
What the site needs to provide
USDA records it across sites receiving 28 to 55 inches of annual precipitation. It needs at least 140 frost-free days to finish its season. It roots to at least 10 inches. Fertility requirement: medium.
Propagating it
Sprigs is the only propagation method USDA lists. Its seed spreads at a slow rate. It spreads vegetatively at a rapid rate.
Resilience and wildlife
Its fire tolerance is rated high. Its growth form is recorded as single crown.
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.
