ATTRIBUTES
Leaves
Leaves are very narrow with a central vein and are longer at the base of the flowering stalk. The leaves look grasslike and get shorter as they climb up the flowering stalk. In non-flowering years, this plant is hard to spot because there are no stems and the leaves camouflage well with prairie grasses.
Flowers
25-40 individual florets are clustered together to form one flowering head. Each flowering stem typically has 10-30 flowering heads. The color is usually light purple but can also be white or pink.
Fruits
The fruits of this species are called achenes and are wind dispersed. Each achene looks similar to a coriander seed with a tuft of brown hairs attached to one end. Every floret produces an achene even if there is no seed inside.
Bloom Time
Flowers can begin blooming as early as late July and may continue into mid-September.
