Desmanthus illinoensis, commonly called prairie mimosa, Illinois mimosa or Illinois bundle flower, is a Missouri native perennial which occurs in prairies, thickets, glades, rocky slopes/open areas and along railroad tracks throughout much of the State. It is an erect, somewhat weedy plant which grows 2-3′ (less frequently to 5′) tall with mimosa-like, compound bipinnate foliage. Globular flower heads (1/2″ diameter) of extremely tiny, 5-petaled, white flowers (30-50 flowers per head) bloom in June-July on short axillary stalks. Projecting yellow stamens give the flower heads a spherical brush appearance. Curved, dark brown seed pods (to 1″ long) develop in clusters (or bundles) on the flower heads in late summer and persist into fall. This pea/bean family plant is noted as an important range plant due to its high protein content.
