Comments:
This native deciduous tree has an interesting trunk where pointed growths occur on the trunk and large branches. Prickles or short thorns are present on the back of the compound leaves that resemble the foliage of ash trees. Autumn color can be quite striking on the toothache tree. Swallowtail butterflies are attracted to the foliage where they lay their eggs.
