Epilobium subdentatum is a fast-growing perennial willow-herb native to mountainous regions of western North America and South America, preferring moist soils in partially shaded spots. It produces small but attractive flowers that draw in pollinators including bees and moths. Plant in a naturalistic or wildflower garden setting for best results, and monitor spread as it can self-seed readily.
