About this plant
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. Its gentle spring display suits shaded garden settings, where the flowers can be appreciated up close along paths or beneath deciduous shrubs before foliage dies back later in the season.

Design tip
Plant this Pacific Northwest native beside shaded paths or beneath deciduous trees where the intricate flowers can be admired up close. Layer native woodland companions, graceful ferns, and contrasting foliage to create a naturalistic planting rich in texture and seasonal character.
