Full sized tree and a fast grower. I have two of these and the one that gets more water is growing more slowly. Other than that it's a pest free tree that just simply grows. Have nothing bad to say about it except I hope it starts to widen out a bit. Seems it's spending it's energy on growing taller. It is planted next to a few 40-45 ft high pine trrees so that may be why it's growing up more than out.

You do need a good amount of room for one of these.
