Fireweed

Honeybees forage on fireweed for its abundant nectar and substantial pollen, making it a key contributor to midsummer honey production in open, disturbed areas. Bloom peaks from June to September, with flowers opening sequentially along tall spikes to provide a prolonged resource. It spreads aggressively via rhizomes in sunny, moist sites and tolerates nutrient-poor soils but may need containment to avoid dominating garden spaces.
