Growing conditions
It needs full sun. USDA rates it as having needs consistently moist ground. Its drought tolerance is rated low. It is recorded on soils from pH 6.4 to 7.2 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 7.
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 September through November. Flowers are red.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is yellow-green, fine in texture. Its flowers are not conspicuous — a plant for form and foliage. It carries conspicuous autumn colour. Its active growth period is spring and 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 30 to 90 inches of annual precipitation. It needs at least 120 frost-free days to finish its season. It roots to at least 12 inches. Fertility requirement: low — no feeding needed on ordinary garden soil.
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.
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 bunch.
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 MUFI3, 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.
