Dalea foliosa, commonly called leafy prairie clover, is a species of flowering plant in the legume family (Fabaceae).

[2] This is a perennial herb growing 20 to 80 centimeters tall, with a number of erect stems sprouting from a hard root crown.

In northern Illinois, where there are disjunct occurrences of the plant, it can be found in sunny, open dolomite prairies and river terraces that are periodically burned in the natural fire regime.

Remaining habitat is overgrazed and invaded by introduced plant species such as Chinese privet (Ligustrum sinense) and Amur honeysuckle (Lonicera maackii).

[4][5] Some plants have been reintroduced to habitat where the species is hypothesized to have occurred in the prehistoric times, including part of Indiana.
