Thistle

A thistle is a flowering plant with sharp spines or prickles on margins of the leaves. Thistles are common in desert areas. As the plants are not suitable for grazing and scapes the legs of hikers, many people consider thistles a weed. Several species of thistles have medicinal uses, and most have pretty flowers.

Most thistles are members of the Asteraceae family.
