Looks like Oenothera laciniata, Cutleaf Primrose. Its a FL native.

Thanks Eric, now that you mention it I thought the flower looks like the primroses from up north that I grew.

I love that little plant. It's so bright and cheerful looking. I see them all the time around here, and have always thought it would make a lovely ground cover for a potted plant.

BTW, I found some tiny little seedling blue-eyed grass growing in our lawn. Almost missed it, the flowers were so tiny, but it had the iris-looking foliage, so I'm sure that's what it is. I put it in a pot and it's doing very well. Of course, it's done blooming now, but it hasn't died yet, so I'm hopeful. I still have my eye on those two big clumps on the shoulder up the road, but I keep forgetting to take my trowel when I walk up there. Probably too hot to transplant now anyway.

DG the 2 clumps of blue-eyed grass that I dug up are also doing really well. I hope they'll come back next year. And I love love all primroses (odnethera). I brought my evening primroses with me and they have adapted very well. The median strips in my area were covered with the pink ones (called specious up north). What a beautiful sight that was…until the county mowed them down…but not before I dug up a bunch :)
