stiff and upright saw-wort is a perennial, growing chiefly in
open woodland, in rough pastures, and in some areas amongst limestone
rocks. It has wiry stems, the leaves on which are finely toothed.
The lower leaves are pinnately divided. Often the composite flower-heads
are arranged in groups of three on the ends of the branches. The
flowers are light purple, or rarely white. They open in late summer
and autumn and are attractive to bees.
