Stunning in bloom, Chamaenerion angustifolium (Fireweed) is a strongly-spreading, rhizomatous perennial wildflower boasting striking spikes of up to 50 or more saucer-shaped, purplish-pink flowers from summer to fall. They sit atop upright pink-tinged stems clad with long, narrow, willow-like leaves. Attracting lots of pollinators, each flower is perched at the end of a long capsule bearing numerous seeds adorned with a tuft of silky plumes. Acting as fluffy parachutes, they can travel away from the parent plant and form dense colonies. A single plant can produce 80,000 seeds! Fireweed can quickly take over a garden if left unattended. Perfect for prairies, meadows and naturalized areas.
