I live in Lake Mary, which is slightly northeast of Orlando. I have had wild coffee for a year, mine is small so on the coldest nights last winter, I covered it with a king size pillow case, came through winter just fine. I have mine in a dappled shade area in the south part of my yard. I remember you were looking for something to provide a little shade, I recently shaped my yellow Cestrum as a small tree and it looks great, plus the butterflies love it. Yellow Cestrum is fast growing and prunes readily, if you are looking for a small amount of shade for some plants that don't like full sun.

Even the worst winters, low 20's, froze to the ground! Come spring, right back up. Have the original I brought with me fourteen years ago, huge after the last two mild winters.
