Seasonal Interest & Wildlife Value

Large white flower clusters appear in late spring, attracting pollinators such as mining bees, flower long‑horn beetles, and flies. By late summer, the flowers give way to berries that birds eagerly devour. Fall foliage puts on a brilliant show — shades of red, maroon, pink, coral, or violet.

Landscape Uses

Plant in the understory of trees, on shaded slopes, or as a suckering thicket for natural screening. Space plants at least 6 feet apart. It’s sold in 2‑, 5‑, or 10‑gallon containers. Berries can be collected and sown directly or in pots.

Deer note: Deer browse spring foliage; fence young plants if deer pressure is high.

Distinguishing Traits

Vase‑shaped form, large leaves that lend a tropical look, and large flower heads. Fall color varies yearly — sometimes solid crimson, other times a mix of pinks and purples.
