Erysimum capitatum var. capitatum var. capitatum
Western wallflower is a cheerful native perennial producing clusters of bright orange to yellow flowers that are highly attractive to early-season pollinators. It thrives in well-drained soils with full sun and tolerates dry, rocky conditions typical of its mountain and prairie native range. Minimal watering and no heavy fertilization are needed once established, making it ideal for low-water native gardens.
