A flat-topped cluster 2 to 5 inches across of 3/8-inch yellow flowers, each with about 10 short petals (ray flowers) and a yellow center.
There are both basal leaves, and leaves alternating up the stem. The basal leaves are up to 5½ inches long and 1½ inches wide and stand generally erect on long stems.
The alternating leaves are progressively smaller as they go up the stem. They have wavy edges, are fairly stiff (hence the name), point upward, and clasp the main stem. All leaves are a grayish green color, generally oval in shape, and are rough from short hairs.
The flowers transform to brown seed with attached fluff to carry them off in the wind.
