Growing conditions
It needs full sun. USDA rates it as having moderate water needs. Its drought tolerance is rated medium. It is recorded on soils from pH 6 to 8.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 7.
Size and growth
At maturity it reaches about 2 ft, making it about knee height. It grows at a moderate rate.
Bloom period
USDA records a bloom period of March through May. Flowers are yellow.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is green, coarse in texture. Its flowers are not conspicuous — a plant for form and foliage. Its active growth period is spring and fall. USDA rates its lifespan as moderate.
What the site needs to provide
USDA records it across sites receiving 30 to 60 inches of annual precipitation. It needs at least 175 frost-free days to finish its season. It roots to at least 20 inches. Fertility requirement: medium.
Propagating it
Propagate it from bare root and sprigs. It spreads vegetatively at a rapid rate.
Resilience and wildlife
Browsing animals find it moderately palatable, so expect deer and rabbits to take an interest. 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 AMAR4, 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.
