I don't. I only know I have it too. Its a native of some sort. I will search native FL plants and see if I can find it. The area it really grows in is under the big power line easement that runs 50 ft on each side of a new power line (actually an old power line that was updated) that goes back from just beyond my property and through MILES of the nature preserve. No one trims or cuts anything back there doe to state regulations for the preserve. They cut down any trees that were tall enough to threaten the power line when they updated it because it runs for over 30 miles through the county and supplies the main power to UF. All the low growing vegetation they leave alone
