Cirsium occidentale

The California Thistle, Cirsium occidentale var. californicum, has grayish-green leaves with spiny teeth, and white, purple or rose colored flowers. It is found in disturbed areas such as vacant lots and roadsides, as well as chaparral, coastal sage scrub, and open areas of woodlands. Thistles are in the Asteraceae or sunflower family. Painted Lady butterflies use species of Cirsium as host plants.
