Erect, cylindric spike 1 to 2 inches long, single at the tips of branching stems, densely packed with tiny pea-shaped flowers. Flowers are 1/6 to ¼ inch long, white to pale pinkish or purple, the upper petal largest and erect to ascending, the lower and lateral petals about half as long as the upper. A column of 9 or 10 stamens with yellow to red tips protrudes from the center. The calyx holding the flower has 5 awl-shaped lobes, 10 ribs, and is covered in long white hairs. Flowers bloom from the bottom of the spike up, sometimes with just a small ring of flowers open at a time.
Leaves and stems:
Leaves are alternate, up to 4 inches long, compound with 15 to 41 leaflets. Leaflets are ¼ to ½ inch long, oblong-elliptic or widest above the middle, toothless, hairless, mostly stalkless, sometimes red-tinged. The lower surface is much paler than the upper and gland dotted, the dots often showing through to the upper surface.
While not considered a rare species in Minnesota, Foxtail Prairie Clover is certainly uncommon. There have been only 3 records of it since 1900, the most recent in 1961 in Lac Qui Parle County. It is considered an adventive species and a bit weedy in the eastern US. It is easily distinguished from other Prairie Clovers by the larger flowers, densely hairy calyx, and gland-dotted compound leaves with numerous leaflets.
