These interesting deciduous trees can grow between 15 to 30 feet tall and have thorny branches and stems. They like full sun and do quite well planted along forest edges, fencing, or waterways. They are related to the Citrus family of trees and their leaves have a lemon scent when crushed. The Giant Swallowtail relies on the Prickly Ash for food for their caterpillars; they love the fresh green foliage. This is a wonderful tree to include around your property.
