Prairie mimosa (also commonly called Illinois mimosa and 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.
No serious insect or disease problems.
Perhaps best utilized in informal prairie or naturalized areas. Native plant gardens.
