Detailed Information

Flower:

Up to 20 flowers are in an open cluster at the top of the plant, and on stems branching from the leaf axils near the top of the plant. Individual flowers are yellow, about 1 inch across, and resemble dandelions.

Leaves and stem:

Leaves change shape as they ascend the stem. There is a rosette of basal leaves, each up to 6 inches long and 1 inch wide, coarsely toothed with a pointed tip and short leaf stem. Leaves on the lower part of the stem are more irregularly toothed or divided with sharply pointed lobes and curled edges.

The stem leaves quickly lose this shape and progressively become smaller and very narrow, toothless, with no leaf stem. Leaves near the top of the plant are less than ¼ inch wide. The main stem is hairy and ridged.
