Becky,
If you could grab a garden budy and rent a car it would be worth a drive to see the Central FL gardens. There are so many in that area: Dan Hansen, Kinnebrew, Lambertson, Nicole Devito, Floyd Cove, Trimmer, Reilly's (I think his wife and daughter are still running it) plus Salter and Petit a little further north. They do a Mecca event the 3rd weekend of May each year. Lots of free food and plants.
