Prickly ash (Zanthoxylum americanum) is a spiny shrub native to woodlands and open slopes of eastern North America. Branched stems are lined with sharp prickles, giving the plant its common name, and aromatic leaves release a citrus-tinged scent when crushed. In late spring and early summer, clusters of small greenish flowers appear, followed by round, yellow-orange berries that hang like tiny ornaments well into autumn.

The bark, berries, and leaves of prickly ash have long been used in traditional medicine. Early settlers and Indigenous peoples brewed teas from the bark for digestive discomfort and circulatory support. The berries were sometimes chewed or steeped to relieve toothache. Ecologically, prickly ash provides nectar for pollinators and food for birds that eat the berries. Its sturdy form and seasonal interest make it a valuable addition to naturalized gardens or open woodlands. Though its spines require careful handling, many appreciate prickly ash for its rugged beauty and historical importance.
