The plant has a habit of colonizing recently burnt sites which is the origin of the common name.

The scientific name of the plant has changed at least three times. In Newcomb’s Wildflower Guide it is called Epilobium angustifolium which has  the second common name of Great Willow Herb. There are several Epilobiums which grow in the Toronto area.

The ROM Field guide calls it Chamerion angustifolium. The most recent field guide Michigan Flora calls it Erichtites hieracifolius. Hieracifolius means with leaves like the Hawkweed plant.

Scientists are always looking for mistakes in the classification of plants and, apparently, Fireweed has been misclassified at least twice.

We blame the origin of many weedy plants such as Ragweed and Dandelion on the other parts of the world, but Fireweed is one of the few North American plants of weedy habit to have become naturalized in parts of Europe.

As long ago as in 1830, Raffinesque described Fireweed as useful in hemorrhage, wounds, headache, inflammations, herpes and diseases of the skin.
