Fireweed

Epilobium angustifolium

flower

A vigorous perennial with tall spikes of magenta-pink flowers that bloom throughout summer, reaching 3–6 feet in height. Named for its tendency to colonize disturbed and burnt areas, it spreads rapidly via seeds and rhizomes in open, moist locations. The narrow, lance-like foliage provides a delicate texture, and autumn color is attractive.
