Blue Globe Thistle

Appearance

The flower heads are almost perfect spheres and made up of small closely packed blue flowers. In between these closely packed flowers sharp spines jut out. They are a little longer than the flowers. Before the flower blooms, it looks like a very spiny ball. The silvery-green leaves are pinnately divided into many segments. The edges of the leaves have sharp spines all along. The leaves are white-cottony beneath.
