Wafer Ash

About Wafer Ash

Wafer Ash, also known as Common Hop Tree, is a fascinating and hardy native understory tree that serves as a vital link in the life cycle of several spectacular butterflies. Growing 15 to 20 feet tall with a spreading, often multi-stemmed habit, it features glossy, trifoliate leaves that turn a clear yellow in the fall. In late spring, it produces clusters of inconspicuous greenish-white flowers that are highly attractive to bees and flies. These are followed by unique, wafer-like winged seeds (samaras) that persist into winter, providing visual interest and food for birds. Native to much of North America, it is found in habitats ranging from rocky slopes to river valleys. Wafer Ash is a primary host plant for the Giant Swallowtail butterfly, the largest butterfly in North America. It is remarkably adaptable, thriving in full sun to partial shade and well-drained, medium-dry to dry soils. Its tolerance for varied conditions and its critical ecological role make it an outstanding choice for woodland edges or wildlife-focused gardens.
