If you’re looking for a unique and resilient addition to your native landscape, the Hercules fast growing native florida trees Club tree (Zanthoxylum clava-herculis) could be the perfect choice. With its eye-catching, spiky bark, vibrant green foliage, and being the larval host of the giant swallowtail (Papilio cresphontes) butterfly, this tree is as captivating as it is hardy. Commonly known as the toothache tree due to its traditional medicinal uses, Hercules Club is native to the southeastern United States, including most of Florida and is well-suited for drought-tolerant landscapes and low-maintenance gardens.
We have several mature Hercules Club trees growing around our farm and native plant nursery. Before moving to our farm in Ocala, I was unfamiliar with this fast growing native tree, but it is quickly becoming one of my favorites native trees of North Central Florida.
Growth Habits
Hercules club is known for its distinct, wart-like knobs along its trunk and branches, giving it a bold, rugged appearance. These “prickles” are a natural defense mechanism, adding a touch of texture that makes it instantly recognizable and even adds a bit of mystery to your yard.
Reaching 10 to 25 feet in height with an open, irregular canopy, Hercules Club tends to have a unique silhouette that provides seasonal interest. Its moderate size makes it a fantastic specimen tree, even in the smallest of yards. It is a fast growing Florida native tree and has greenish-yellow flowers bloom in spring and summer, attracting a variety of pollinators, including butterflies and bees. By fall, the small, dark fruits it produces become a food source for birds, adding another layer of ecological value. One of my personal favorite characteristics of the Hercules Club tree is its delicious, citrusy scent.

Historical Uses of Hercules Club
The nickname “toothache tree” comes from the tree’s historical medicinal uses. Native American tribes and early settlers would chew on the bark to relieve toothaches due to its numbing properties, which were later attributed to compounds in the plant that act as mild analgesics. Today, it’s more commonly enjoyed for its ecological and ornamental benefits, but its medicinal uses are still utilized by many. As always, be sure to do your research before utilizing new medicinal plants. Florida’s Incredible Wild Edibles by Richard Dueling and Peggy Lantz is an excellent resource.
