As the first poster indicated, there are two "general" gardening clubs here. Both meet on the 2nd Wednesday of the month at 9 A.M. The Villages Garden Club meets at La Hacienda Center and The Villages Garden Club North meets at Mulberry Grove Center. There are no dues.
There is also The Villages Rose Club that meets the 3rd Wednesday of the month at 9 A.M. at Laurel Manor. Here's their website:

I believe there is also a club that concentrates on bonsai but I can't find the info on it right now.
I think you will love playing in the dirt here - there certainly are a lot of us that do. The plants that you know from "home" that do grow here, grow
much bigger, and flower earlier and longer. Many northern annuals are perennial for us. There is also a bounty of plants that will be new to you and, if you love gardening, you'll quickly find that your garden area is too small and you'll remove a little more grass here and then a little more grass there to make room for just one more plant here and one more plant there, etc.
Welcome and best of luck in your search.
