Had a real bumper crop of Lychee this summer. Most years I only get a handful on my almost 20 year old group of 3 trees. The tree were planted in a triangle quite close together. They are about 20 feet tall and about 15 feet wide. They have long since grown together and look like just one tree from a distance. The Lychee trees were planted right next to 3 Longan tree. We get lots of Longan fruit every year.
