Discussion

Serpentine and non-serpentine gravelly slopes. Flowering Mar–Jun. 400–2100m. Casc, Sisk. CA. Native.

Fritillaria glauca is our only species that grows in serpentine soils. This species also grows in non-serpentine habitats. This begs the question: Was F. glauca historically a serpentine or non-serpentine endemic? The sickle-shaped and strongly glaucous leaves of F. glauca are distinct among Oregon fritillaries.

Grassy or shrubby areas, open woods, often on slopes. Flowering Mar–May. 0–2600m. BR, BW, Casc, Col, ECas, Lava, Owy, Sisk. CA, ID, NV, WA; north to British Columbia and Alberta, east to NB, southeast to NM. Native.

Fritillaria pudica is unique among Oregon species within the genus because of its unmottled perianth segments.
