Fireweed Chamanerion angustifolium Onagraceae Spokane Region Native Full sun to part shade 4–6 ft tall (can reach 8 ft); spreads laterally by rhizomes Drought Tolerant: Moderate, p refers at least spring moisture Evergreen: no Flower: Rosy magenta-pink (occasionally white) (June–September) Rich nectar source for hummingbirds, butterflies, native bees, and hawk moths; larval host for the White-lined Sphinx moth and other lepidoptera; young shoots and foliage browsed by deer, rabbits, and other mammals Fireweed is a tall, vigorous perennial native throughout the northern hemisphere, growing naturally in open disturbed areas, burned forests, clear-cuts, roadsides, and moist meadows. It spreads from persistent underground rhizomes and produces enormous quantities of windborne seeds, allowing it to rapidly colonize disturbed ground. In the Spokane region it thrives in full to part sun and is highly adaptable to most soils — from moist riparian margins to drier slopes — though it performs best with at least moderate moisture. Once established, it is remarkably hardy and can handle Spokane's hot, dry summers, particularly in lower-traffic areas where soils remain slightly moister. Fireweed is one of the most visually arresting plants in the Pacific Northwest landscape. Tall, upright red-tinged stems carry slender alternate leaves and terminate in long tapering spikes of four-petaled magenta-pink blossoms, each about an inch across. A single spike may carry up to 50 blooms, opening progressively from the base upward, providing weeks of color from midsummer through early fall. As flowers fade they are replaced by slender seed pods that split open to release clouds of silky white tufted seeds — a spectacular late-season display. The foliage often takes on warm orange and red tones in autumn before dying back. Fireweed carries significant ethnobotanical importance across Pacific Northwest and boreal Indigenous cultures. Young shoots and leaves were eaten raw, boiled, or steamed as a nutritious spring green by Alaska Native, Bella Coola, Clallam, and many other peoples. Stems were split to harvest the edible pith and the tough fibers processed for making twine and fishnets. A poultice of roasted roots was applied to treat skin boils, and infusions were used for digestive complaints. For wildlife, fireweed functions as a keystone early-successional species: hummingbirds rely on its nectar, bees prize it for high-quality honey production (fireweed honey is commercially prized in Canada and Alaska), and the White-lined Sphinx moth and other lepidoptera use it as a larval food plant. In the landscape, fireweed is best suited to naturalized or semi-wild areas where its spreading habit can be appreciated rather than controlled. It makes a dramatic statement in rain gardens, along fence lines, at forest edges, or in large wildflower meadow plantings. Because it spreads vigorously by rhizome, plant it in areas with thin, drier soils or where it can intermingle freely with other robust natives. Excellent companions include Nootka Rose (Rosa nutkana), Snowberry (Symphoricarpos albus), Douglas Aster (Symphyotrichum subspicatum), and Canada Goldenrod (Solidago canadensis). Avoid planting directly adjacent to delicate perennials it may overrun. It is particularly beautiful when massed along slopes or intermixed with native grasses such as Blue Wildrye (Elymus glaucus).
