Prickly Sour Thistle

Asteraceae, sonchus asper
sharp-fringed sow thistle, spiny show thistle
A member of the sunflower family.
NOT a CA native. The leaves are edible. Hmmm.
The leaves are bluish-green, simple, lanceolate, with wavy and sometimes lobed margins, covered in spines on both the margins and beneath. The base of the leaf surrounds the stem. The plant can reach 180 cm (6 ft) in height. The leaves and stems emit a milky sap when cut. The flowers grow in clusters and the end of the stems. (wikipedia)
