|Genus:|| Lithophragma (Nutt.) Torr & A. Gray|
|Species:|| Lithophragma parviflorum (Hook.) Nutt.|
Perennial herbs from rhizomes with small bulblets, densely hairy throughout.
Overall leaf shape orbicular to reniform, leaves 3-5 times palmately divided nearly to the base, then again lobed 2-3 times.
Inflorescence a raceme, corolla consisting of 5 petals, which are generally 3-lobed. Calyx at anthesis is vase-shaped, ovary at least 2/3 inferior. Stamens 10. Stigmas have a narrow ring of hair just below tip.
Plants along the coast in Washington and Oregon appear to have distinctly purple- and pink-tinged petals.
3-beaked capsule, bearing seeds which are smooth or slightly wrinkled to reticulate, but never with prickles.
BC southward, on both sides of Cascades, to northern California, east to Alberta, the Dakotas, and Colorado.
Prairies, balds, grasslands, sagebrush desert, and open forest, sea level to mid-elevations.
Seeds should be planted in late summer or fall following their collection. Long term seed storage is not recommended. Can be grown by seed or bulblet. Plants go dormant immediately after seed matures. No stratification processes are needed.
Seed sample from: 2010
Average Measurement: 0.5 x 0.3 x 0.2
Measurement Range: L: 0.3 - 0.6, W: 0.1 - 0.3, D: 0.1 - 0.6
Shape: Seeds very small, hilum puckered, and located at tapered end of seed. Opposite apex also tapered.
Color: Seeds dark brown, and almost black at ridges and wrinkles.
Surface: Seeds have at least one major ridge that extends longitudinally from hilum to opposite apex. Seeds may have some other longitudinal ridging and wrinkling. Seeds very shiny, smooth, and iridescent.
