Well, first off, all trees have branches of some sort. Second, are we talking about pines or something more spruce or fir?
The most common skinny pine in Florida is called a Slash or Longleaf pine. Is this what you are talking about?
I think it would be rare to find Longleaf Pine at a Home Depot but a local nursery should have them or guide you to where to find them. They look like this when young.
