fireweed, (Epilobium angustifolium), perennial wildflower, in the evening primrose family (Onagraceae), abundant on newly clear and burned areas. Its spikes of whitish to magenta flowers, which grow up to 1.5 m (5 feet) high, can be a spectacular sight on prairies of the temperate zone. Like those of many weedy plants, its seeds can lie dormant for many years, awaiting the warmth necessary for germination. Fireweed is one of the first plants to appear after a forest or brush fire; it also rapidly covers scrub or woodland areas that have been cleared by machine.

Fireweed has limited use in wild gardens, where it must be carefully checked and confined. The willowlike young shoots and leaves can be cooked and eaten.
