Prairie flax grows 18–20 inches tall. It rarely stands straight up, but rather leans at an angle. Flowers are pale blue, with 5 petals about 1–1 1/2 inches across, veined in darker blue. Each stem produces several flowers, blooming from the bottom upward. The seeds are produced on the lower flowers while those above continue to bloom. The stem is leafy when the plant is young, gradually losing most of its leaves as it matures. Leaves are narrow and about 3/4 inch long.
Pretty little flowers that remind me a little bit of the periwinkle bloom (mainly the color). I’ve found them sparsely dotted over the North 40 and they seem to have a short life span.
