Rosebay Willowherb

Rosebay willowherb, Chamerion angustifolium (also known as Epilobium angustifolium) is a widespread plant of the Northern Hemisphere.

Known as Fireweed to many, particularly in North America, this name reflects the plant’s appearance following forest fires and other events which leave the earth scorched. With greater light on the earth again, C. angustifolium seeds then germinate and grow in the cleared areas until competition crowds them out.

Habit and Habitat
The plant is an upright perennial, with an unbranched stem growing to around 1.5 metres (4.5 feet), sometimes taller, with pink or purple four-petalled flowers. The leaves are alternate and resemble those of some Willows, Salix sp.
