Taxonomic Notes

Asarum caudatum is from the mountains of western North America including BC. It has attractive, somewhat glossy, kidney-shaped foliage which combines well with lacy ferns and bleeding hearts. Intriguing brownish-red flowers appear beneath the foliage so make sure to watch for them.
