Narrow-leaved milkweed

Description:

"Narrow-leaved milkweed is the most widespread species in California, growing in every region of the state except the Sonoran Desert and the upper montane, subalpine, and alpine zones of the Sierra Nevada. Suitable locations include dry to moist soil in open, sunny areas. It is typically found in plant communities such as valley grasslands, wetland-riparian areas, foothill woodlands, and chaparral, and clearings within yellow pine, red fir, and lodgepole pine forests."
