Zanthoxylum americanum

Common name: Prickly Ash

Native plant

Prickly Ash is part of the oak savanna. It is a very thorny plant that grows into thickets that are impossible to penetrate. The seeds are jet black and have a very strong citrus smell. I have crushed the seed with my hands and smelled like citrus all day. Prickly and Wafer Ash are the major food source for the Giant Swallowtail butterfly. This plant likes full to half-day sun. Fall color is yellow.
