Pacific Waterleaf

hydrophyllum tenuipes

Pacific Waterleaf (Hydrophyllum tenuipes) is a lush, shade-loving perennial herb native to the moist, deciduous forests of the Pacific Northwest. Characterized by its large, deeply lobed leaves and delicate clusters of bell-shaped flowers, this plant serves as a vital component of the forest understory. It thrives in rich, damp soils, often spreading via underground rhizomes to form extensive, vibrant green carpets that stabilize the forest floor and provide shelter for various microfauna. During spring and early summer, its distinctive flowers emerge with prominent, thread-like stamens that give the blooms a fuzzy appearance. Historically used by Indigenous peoples as a food source, the tender young shoots and roots were cooked and consumed.

Habitat: Found in moist, shaded forests, damp woodlands, and riparian zones, typically in nutrient-rich soils at low to middle elevations.

Appearance

This species features large, alternate leaves that are deeply divided into 7 to 9 sharply-toothed, palmately lobed segments with a rough, hairy texture. The plant grows to heights between 20 and 80 cm, forming dense mounds of soft foliage. Its flowers are clustered in coiled, cyme-like inflorescences and are usually greenish-white, lavender, or cream-colored. Each bell-shaped flower is about 5 to 7 mm long, notably characterized by long, protruding stamens that extend far past the petals, creating a delicate, whiskered look.
