This gravel prairie contains a large number of plant species, including several that are threatened or endangered in Illinois. One of the most remarkable features of this preserve is the large number of prairie wildflowers, especially pale purple coneflower. Pasque flowers can be observed here during the spring. The rare plants that are found here are the pink milkwort, downy yellow painted cup, Hill's thistle and prairie buttercup. Harlem Hills is Illinois' largest and finest remaining example of a gravel hill prairie.
