Plant suggestion?

Plant suggestion?

I know things are slow this time of year but I thought I'd go ahead and pose a question, even if I don't get around to planting till later. I live in north Florida, zone 8B, and I have a small area by my driveway/gate that is begging for a plant. It's a difficult spot - it's shady, sandy, and usually dry except for when it rains (the gutter spout is right next to it so I'm sure it would get overflow). Any suggestions?
