Distribution | ||
Discussion | Roadside ditches, edge of woods. Flowering May–Jun. 0–200 m. Casc, Est, WV. ID, WA; scattered across northern US and southern Canada; Europe. Exotic. McNeill (1979) noted that the earliest collection of S. dioica in the western United States was made in Portland in 1905. This species is sometimes cultivated, and it can escape from such settings. Silene dioica and S. latifolia are interfertile, and hybrid plants (S. ×hampeana) with pale pink petals can be expected. |
Rocky, alpine slopes. Flowering Jun–Aug. 1000–2300 m. Sisk. CA, NV. Native. Morton (2005) noted that small, alpine plants of S. parryi may be mistaken for S. grayi. |
