- Description
-
Spreading Dogbane is an herbaceous perennial wildflower that is widespread across North America and is found in the mountains of NC in a forest, woodland, forest edge, prairie, meadow or field site. There are numerous small pink, nodding, bell-shaped flowers that are fragrant and striped inside with deeper pink. It grows 2-3 feet tall as a bushy shrub or perennial and spreads quickly from underground rhizomes making it inappropriate for small gardens.
This plant prefers average to dry conditions in barren sandy to rocky soils but tolerates loams in sunny to shady conditions. It was once thought to be a monarch butterfly host plant but larvae deposited there do not survive. However, the nectar is a good food source for pollinators.
Plant in a woodland or pollinator garden or naturalized areas.
