Flower:

Open panicles of showy blue dandelion type flowers, ½ to 1 inch across. Flowers have 14 to 50 rays (petals) with 5 small teeth at the tip and fading to white at the base. Each ray has a blue divided style and a blue stamen at the base. Elongated overlapping bracts form a cylindrical tube around the base of the flower.

Leaves and stem:

Leaves are oblong to lanceolate, 3 to 6 inches long, ½ to 1½ inches wide, sometimes with a few pairs of lobes on the lower half, usually the lower leaves. The few basal leaves are stalked, stem leaves are stalkless or clasping, toothless or marginally toothed, smooth on the upper surface, sometimes with a fine waxy bloom underneath. Stems are slender, smooth or finely hairy at base, and leafy up to the panicles.

Fruit:

Fruit is a dandelion type plume of small ribbed red-brown seeds with bright white fluff to carry them off in the wind.

Notes:

This species was formerly in the Lactuca genus, going by a number of names: Lactuca tatarica, Lactuca pulchella, Lactuca oblongifolia. The flowers are much like Chicory (Cichorium intybus) but Chicory has much larger flowers, is a taller plant, and the clusters are more like elongated spikes, not a branching panicle. While widespread throughout Minnesota and North America this species is not one we've commonly encountered. Its frail demeanor and usually sparse dispersal within its habitat could be reasons it may not stand out and catch the eye, but you might also be lucky enough to encounter a swarm of it.
