Answer: Jacaranda acutifolia is the lavender-blue flowering cultivar, growing 25'-40' tall and 15'-30' wide. It has an open, multitrunked or shrubby habit, and finely cut, fernlike leaves. It's a hardy plant, to 25F degrees, so should grow well in your area. Jacaranda is truly a spectacular tree. Plant it in full sunshine and supply one-inch of water per week to help it become established. Once established it won't require much water - just a thorough soaking once or twice during the hottest summer months.
I'm not aware of any books published specifically on the Jacaranda tree, but here's the website address of a Jacaranda Research Group. It contains a link to publications: http://www.cs.adelaide.edu.au/~jacaranda/generate.php?title=...
Best wishes with your tree!
