Hydrophyllum tenuipes, the Pacific waterleaf, is an herbaceous perennial plant native to North America.

It is found in western North America from British Columbia to northern California.

The Hydrophyllum tenuipes plant spreads by rhizomes to form large colonies in wooded areas.

There are numerous clusters of flowers on stalks extending from upper leaf axils.

[1] Hydrophyllum tenuipes grows at low to mid elevation in shady conditions often in close association with Tolmiea menziesii (Youth on Age), which blooms during the same period.
