Description
A somewhat hairy perennial, the leafless flowering stems usually growing singly from a rhizome, reaching 10-30 cm in height.
Leaves for a basal rosette, and have smooth margins, a visible center vein, and are rounded.[2]
The inflorescence is a short, compact panicle, subtended by a leafy, rusty-woolly bracts. The calyx is broadly conic, the 5 lobes oblong-lanceolate, 1-2 mm. long and reflexed. Individual flowers have 5 white, obovate petals, 1.5-3 mm. long, at least half as broad as long. Stamens number 10 and are short, awl-shaped.[3]
Ovaries are green and can turn red as fruit attached.[2]

Late March - July[3]
Distribution
West side of the Cascades, British Columbia to Lincoln County, Oregon, and in the Columbia River Gorge[3]
Habitat
Prairies, grassy slopes and vernally moist areas, sea level to subalpine[3]
Swamp saxifrage prefers moister areas in prairies, such as near a stream or at the base of a tree.[2]
Uses
Used ornamentally in rock gardens
