Growing conditions

It grows in partial shade. USDA rates it as having moderate water needs. Its drought tolerance is rated low. It is recorded on soils from pH 5.9 to 7.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 4.

Size and growth

At maturity it reaches about 3 ft, making it roughly waist to chest height. It grows at a moderate rate.

Bloom period

USDA records a bloom period of July. Flowers are yellow.

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 spring, summer, fall. 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 45 inches of annual precipitation. It needs at least 100 frost-free days to finish its season. It roots to at least 8 inches. Fertility requirement: medium.

Propagating it

Propagate it from seed and sprigs. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. 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. 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.
