Description Pacific Waterleaf is an aggressive rhizomatous spreading native groundcover capable of competing for space with English ivy.

  Morphology:
This herbaceous groundcover grows to a height of 1’- 2’ and can spread out even wider via a fibrous rhizomatous root system.

Leaves can be up to 12” long and 8” wide, with 5-9 pinnate to odd number of deeply cut, toothed lobes with sharp points. Soft hairs on the leaves make them feel fuzzy.

Flowers consist of cream, greenish, lavender or blue bells in bell-shaped cymes. The stamens of the flowers extend well past the floral tissue.

  Adaptation:
Waterleaf occurs in middle to low elevation forests from southwest British Columbia to northern California. Growth is best on moist and wet sites.

  Pests:
None reported.
