Foliage, flower and season

Summer foliage is green, coarse in texture. Its flowers are conspicuous. It carries conspicuous autumn colour. Its fruit or seed heads are conspicuous, extending interest past flowering. Its active growth period is spring. 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 23 to 32 inches of annual precipitation. It needs at least 365 frost-free days to finish its season. It roots to at least 36 inches. Fertility requirement: medium.

Propagating it

It takes readily from seed, cuttings, container stock and sprigs. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. It spreads vegetatively at a moderate rate.

Resilience and wildlife

Browsing animals find it moderately palatable, so expect deer and rabbits to take an interest. Its fire tolerance is rated medium, and it can resprout after damage. Its growth form is recorded as rhizomatous.
