Elephanthead Lousewort (Pedicularis groenlandica) is a perennial forb native to Western and Northern US states (such as Washington, Oregon, Colorado, Montana, and Alaska) that can thrive in USDA Zones 2–6. Reaching a mature height of 1–2 feet with an upright stem growth habit, it features fern-like, deeply lobed green foliage and produces dense spikes of pinkish-purple flowers shaped like elephant trunks. It thrives in cold, wet mountain meadows, bogs, and stream banks and is ideal for high-altitude wetland mitigation, subalpine riparian restoration, and native bee support.
Erect fibrous‐rooted perennial, up to 30 in. tall, with fern-like leaves and showy pink flowers (occasionally white) resembling an elephant’s trunk and ears. High moisture requirement, growing in wet meadows, seeps and along streambanks at 2,500-13,000 ft. elevations in the western U.S. and Canada, often in large colonies. Parasitic on adjacent wetland plants.
