Milk Thistle. Milk thistle (Silybum marianum) has spiny pale green leaves with white veins, and the hairs on its seeds are long but not branched like those of Cirsium species. Milk thistle is a robust plant; it is biennial in USDA zones 7 and above, can survive frosts, and grows fast, quickly reaching 4 feet in height and 3 feet or more in spread. It does particularly well in rocky soils near coastlines, although it isn't very tolerant of exposure to sea spray.
