About plant names...

Fireweed is a North American native plant. It is a robust colonizer of newly exposed land, such as that left behind from forest fires, and can carpet huge areas with its brilliant pink flowers.

Identification: Plants reach 20-98" (50-250 cm) in height, with a single, erect stem that reddens later in the season, sometimes branching to multiple flower spikes. Spikes are 4-10" (10-25 cm) long, with pink flowers about ½" (1.3 cm) in diameter, each with four petals. Leaves have smooth edges, and are long and narrow, tapering to sharp tips. The leaf veins form distinctive circular loops. Seed pods are reddish-brown, about 1½" (3.8 cm) long, splitting and curling when dry to expose silken fibers and about 80,000 seeds per plant.

Edibility: Although young shoots and flowers are edible, young plants are easily confused with several highly toxic members of the lily family, so we don’t recommend that you experiment.
