If you’re back from the ocean quite a ways and have a few hills, might want to wander through any heavily shaded, wooded areas that you have just to check anyway. Looks a lot like Virginia Creeper or even Poison Oak. Clusters of five leaves, with red berries.
Interestingly that pretty much describes the area I live.
I was born in Walton County which has the highest point in Florida. It is less than 400 feet tho surprisingly hilly. Hilly as in rolling hills.
I got to thinking about it and probably no point in it tho. I grew up in a rural area which would probably be about the most likely place for it, yet I have never heard of gensing in this area.
