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.
