Western Wallflower (Erysimum capitatum) is a bright, biennial to short-lived perennial wildflower native to a wide range of North American habitats—from dry grasslands and desert slopes to subalpine meadows and forest openings. It is well known for its striking clusters of four-petaled, golden-yellow to orange flowers borne on tall, slender stems above narrow, lance-shaped leaves. This adaptable species brings early color to wild landscapes and pollinator gardens alike, thriving in both disturbed and natural areas with minimal input.
 
Western Wallflower plays a vital role in supporting native pollinators in dry, sparse habitats. Its flowers are rich in nectar and attract a variety of bees, butterflies, syrphid flies, and occasional moths. In higher elevations, it serves as an important floral resource for emerging pollinators when few other species are blooming. The plant also functions as a larval host for certain checkered and cabbage white butterflies. Its ability to reseed and naturalize makes it a valuable component of restoration seed mixes for erosion control and habitat diversity.
 
Western Wallflower prefers full sun and well-drained soils and is especially tolerant of dry, rocky, or sandy sites. It germinates readily from seed, with a brief cold stratification period improving success. Fall sowing is ideal, allowing overwintering seedlings to bloom in their second year.
