It flowers mid to late summer, each successive flower blooming just above the one below it until the last flower at the top of the stalk has bloomed. By that time the bottom flowers turn to a cotton seed ready to be carried by the wind. Alaskan lore states once all the seeds turn cottony, six more weeds til winter. In Alaska, candies, syrups, jellies, and ice cream are made from this flower, the nectar has a distinctive spiced flavor.
My fireweed are a little short this year because I discovered I need major pruning of the canopy above, not enough light is reaching these poor little guys. Our one lone plant has multiplied to about 12 stalks because once it is established it will spread by a long root. My neighbors comment on this purple/pinkish flower, it's always the next show after the day lilies.
