Summer foliage is green, medium in texture. Its flowers are conspicuous. Its fruit or seed heads are conspicuous, extending interest past flowering. Its active growth period is fall. Its winter foliage is dense, which makes it useful for year-round screening. USDA rates its lifespan as short, so plan on replacing or resowing it rather than treating it as permanent structure.

Propagating it

Seed is the only propagation method USDA lists. Division and cuttings are not listed as options. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. Its seed spreads at a moderate rate.
