Cup Plant is a 4' to 8' tall native perennial that has large, opposite, coarse toothed leaves all the way up the stalk. The opposite leaves are united around the stem to form a cup that actually holds water. The terminal flower heads have large 3" wide light yellow rays and darker disk flowers in the center. This plant is easily grown in rich, medium to wet soils, full sun or part shade, and will tolerate some drought after establishment. Cup Plant is an effective backdrop plant in a perennial garden and is used in moist wildflower gardens and meadows and in moist open woodland sites. It produces a gummy sap when broken like the other Silphium species.
