Distribution | ||
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. |
Dry or grassy slopes, often under trees or bushes. Flowering May–Jul. 100–2500m. BR, BW, Casc, ECas, Owy, Sisk. CA, ID, NV; east to ND and NB, southeast to NM. Native. |
