It is the floral emblem of Yukon, Canada and (as rosebay willowherb) the county flower of London, England. The common name derives from the fact that it is a fire follower, often covering immense areas in the first years following a forest fire.This plant is included whenever you see a photo of colorful wildflowers from Alaska or Newfoundland or, indeed, northern climes throughout the world. The subspecies circumnagum is the sole subspecies found in California. Photographed at Regional Parks Botanic Garden located in Tilden Regional Park near Berkeley, CA.
