Pseudotrillium rivale

Brook Wakerobin

Pseudotrillium rivale produces nodding, bell-shaped flowers in early to mid spring, each composed of three white petals finely speckled with maroon or purple markings. The blooms hang delicately above broad, softly textured green leaves, with yellow stamens held within the downward-facing flower. Subtle variation in speckling intensity is common, giving each blossom a lightly mottled appearance rather than a uniform pattern.

Native to the Pacific Northwest, this woodland perennial is associated with moist forests and streamside habitats of southwestern Oregon and northern California.
