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]

Bloom Period

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

Propagation

Can be propagated by seed, division or cuttings.
Seed should be planted in winter and barely covered. Germination takes place in 1 to 3 months at 16-21°C
Division should be done after flowering.
Cuttings in should be taken in late summer.[4]

Seed

Average Measurement: 0.8 x 0.4 x 0.3

Measurement Range: L: 0.6 – 0.8, W: 0.2 – 0.5, D: 0.2 – 0.4

Features

Shape: Seed narrowed at hilum and opposite apex, forming points. Middle between hilum and opposite apex rounded. Hilum is puckered.

Color: Seeds golden brown, and slightly darker at hilum.

Surface: Seeds bumpy and longitudinally ridged. Seeds are slightly lustrous.
