Hairy willowherb is a common wildflower that is native to Europe and Asia. It is known by several other names including fireweed, great willowherb, or rosebay willowherb. Fireweed is the most common name for this plant due to its ability to quickly colonize burned areas after a wildfire. This plant can grow up to nine feet tall and has long, thin leaves and magenta flowers. The plant can be used for making tea, and its leaves can be used to treat inflammation. Some of the other synonyms for hairy willowherb include bombweed, devil's tail, and purple rocket.
