fast growing shade tree
We moved into a new house with no shade trees and it is HOT here in Pasadena! We are only living here for the next 8 years so I'd love to plant trees that will provide shade quickly! AND I would love to find trees that don't lose their leaves in the winter because it can be hot here year-round. Would love to have a shady backyard.
I am very interested in Royal Empress Paulownia (30 ft in 3 yrs!) BUT they lose their leaves in the Winter. Other fast-growing trees are crepe myrtles (but only 3-5 ft/year). (I've been looking on the web page http://www.fast-growing-trees.com)
Or -- because it's such a mild climate, do trees NOT go dormant or lose their leaves in the winter??
And, of course you know that it doesn't rain here about April-October.
Thank you! I'm new to southern California!
