Linda, I don't know that area well enough to know what's there but I'm sure others on this forum do. However, I would suggest you redo the posting on the regular Florida Forum Discussion page because a lot more people regularly visit there. I'm sure you'll get responses on that page. Kate

One of our favorite places...We go to Ft. Myers every winter and always, always visit Sanibel....And, Flamingo, oh Pine Island...There is a little place way at the end of the island that serves the best grouper...When we 1st "found" the place it didn't even have screens on the windows but they have fixed it up and there are times, you can't get a seat. Not sure of the name, but next stop would be in the bay....Wonderful food......

The Florida plants are more likely Cnidoscolus urens. We have C. texanus in this area, and I thought there was no way that it could be related to that sweet-looking plant above. However, if you click on the OP's photo, you can see the stinging hairs. I also learned that two of its common names are Finger Rot and Tread Softly. That plant should probably be avoided. I might as well show Cnidoscolus texanus for comparison. There's nothing subtle about that one being armed. Those are larger plants, at 1-2+ feet tall.

lgmd, I can't get over the size of your American Elm tree!! That man at the base looks like an ant!!! So sorry you lost it. :(
