About

Chamaenerion angustifolium is a perennial herbaceous flowering plant in the willowherb family, Onagraceae. It is known in North America as fireweed and in the British Isles as both fireweed and rosebay willowherb. It is also known by the taxonomic synonyms Chamerion angustifolium and Epilobium angustifolium. It is native throughout the temperate Northern Hemisphere, including large parts of the boreal forests.

Where it grows

This plant is found throughout the northern hemisphere, from 30° to 68°, but is most common in temperate climates. The species is present in the Pannonian macroregion, confirmed with herbarium specimens.

Uses

The plant is not considered palatable, but the young shoots and leaves can be cooked and eaten. Fresh leaves can be eaten raw. The young flowers are also edible (being made into jelly in the Yukon) and the stems of older plants can be split to extract the edible raw pith. The root can be roasted after scraping off the outside, but often tastes bitter. To mitigate this, the root is collected before the plant flowers and the brown thread in the middle removed. The stem centers can also be prepared by splitting the outer stalk, and eaten raw.
