The native Wafer Ash is common in our area. It prefers full sun to light shade and slightly moist to dry rocky or sandy soil. Habitats include slightly moist to upland deciduous woodlands and woodland edges and openings. This shrub is up to 20' tall with a central trunk up to 6" across. Alternate trifoliate leaves are produced on new stems with leaflets 2-4" long and 1-2" across. Occasionally, umbel-like panicles of flowers are produced that are 2-3" across. Individual flowers are a little more than ¼" across with 4-5 whitish (or yellowish green) petals.
