I have a Don Gillogly which is a new variety with a lot of hype, but I decided to give it a try. It's supposedly self pollinating. Sun exposure isn't a problem out here, rather proctecting the tree from the sun and heat is the challenge. I'm considering giving Holiday a try which is another dwarf type tree, but we'll see how the Gillogly does over the summer. It won't cool down out here until October.
