hello, we're in zone 7-8 (DC area) and are landscaping around our pool
this year. at the far end, we'd like to put something that would be
our showcase tree (slow growing and not too large(20ft max)) and are
looking for ideas. the area would receive full sun and we plan to
install sprinkler. would appreciate any thoughts to research on.

thanks!
