Petasites frigidus, commonly known as Arctic sweet coltsfoot, is an herbaceous perennial native to riparian zones, wet meadows, and moist, shaded ground in the Arctic and cool temperate regions of the Northern Hemisphere, including northern Europe, Asia, and North America. It typically forms colonies with upright flowering stems 4-8 inches tall, bearing clusters of yellowish-white to pink flowers in early spring before the leaves appear. The large, rounded, basal leaves rise directly from the rootstock after flowering and can create a dense ground cover.

Arctic sweet coltsfoot is valued for its early spring flowers and its ability to thrive in wet, shady conditions, making it suitable for rain gardens, streamside plantings, and naturalized areas. It is also used in traditional medicine, although caution is advised due to the presence of toxic pyrrolizidine alkaloids. In cultivation, it prefers consistently moist soil and can tolerate partial to full shade. While it is low-maintenance, gardeners should be aware that it can spread aggressively via rhizomes, potentially becoming invasive in favorable conditions.CC BY-SA 4.0
