Chamerion angustifolium (L.) Holub
Fireweed, Willow herb, Great willow herb
Onagraceae (Evening-Primrose Family)
USDA Symbol: CHAN9
Pink spires of flowers bloom at tops of tall, erect, leafy stems with narrow willow-like leaves.
Often grows in spectacular dense patches, and though attractive, it is aggressive in a moist garden, spreading from persistent underground stems. The seeds are dispersed far and wide by long, white, silky hairs. Bees value it as a source of nectar, and the very young shoots and leaves can be eaten as cooked greens. Recent work at the genetic level has shown that Chamerion, recognized by its alternate leaves, is distinct from Epilobium (with leaves opposite, at least near base), the genus in which Fireweed was formerly placed.

Native Habitat: Disturbed soil in cool areas, from the lowlands well into the mountains, frequent along highways and in burned areas; hence one common name.
BenefitUse Wildlife: Attracts bees, moths and hummingbirds.
Use Other: Older stems have been split lengthwise to scrape out the soft, edible centre (pith) and to prepare the tough stem fibres for making them into twine and fishnets. (Kershaw)
