Fireweed (
Chamerion angustifolium
) is a native perennial herb in the Onagraceae (Evening Primrose) family that grows primarily in the Sierras and North Coast Ranges, with scattered locations elsewhere in the state. It is a pioneer species that is most often seen in burned forest areas. After fire or disturbance is can become the dominant species in an area. As trees and large shrubs return, Fireweed disappears. The attractive flowers have four magenta to pink petals, 2 to 3 cm in diameter, and have a resemblance to some
Clarkia species
. It is very hardy and it said to survive in areas of oil spill. It is not often seen in residential gardens but is useful in restoration projects or to rapidly fill in a large, bare area.
