Chances are this will be a duplicate, and I can't post photos yet, so apologies in advance...
We have a small tree in our new backyard in SW FL. It's partially hidden behind a sea grape plant that will be removed as soon as I can. The tree in question is maybe 10 feet tall, fairly stringy (for lack of a better word). There are two main trunks, but each is only a couple of inches (if that) in diameter. The branches are long and thin, the leaves about 1 1/2" long, smooth and shiny. At the end of many branches is a single red flower. From a distance, it looks like a parachutist hanging around - there is a single long stamen (I think) about 3 inches long, and the petals are feathery, and curving back up towards the sky. There have been flowers since I think at least around June when we moved here.
Thank you, Niall C, for the photo tip. Here's a photo of the flower and the main trunk of the tree:
