Rosebay willow-herb flowers (Epilobium angustifolium) growing in the wild. These perennial plants, also known as fireweed, produce rose-purple flowers from summer to early autumn. They are found in or near open woodland and seed readily, quickly becoming a pest when planted in gardens. Photographed in British Columbia, Canada.
