Buttonsage occurs naturally along coastal strands, dunes, hammocks, and pinelands in coastal counties from Pinellas (on the west) and Brevard (on the east) south to Monroe and into the Keys.

Garden tips: Buttonsage is an excellent addition to tropical and subtropical butterfly gardens as its nectar is attractive to a variety of butterflies and other pollinators and it blooms year round. It is drought- and salt-tolerant. It also works well as a hedge plant.
Caution: Do not confuse this with its non-native relative, Lantana camara, which has larger, more colorful blooms, but is highly invasive and thus should be avoided. Lantana camara is the species typically found at big box retail garden centers. Be sure to inquire with staff to ensure you are purchasing the native species, or visit a nursery that specializes in native plants. Visit PlantRealFlorida.org to find a nursery in your area that specializes in native plants. For more information on the invasive Lantana camara, visit the UF/IFAS Center for Aquatic and Invasive Plants’ species page.
