I'm actually here just for the tree ID starting with this one that brought me when I searched for tree ID forums. Although I've never actually seen one it is probably a black poui, Jacaranda mimosifolia D. Don, which is the most common cultivated species in the genus. The foxglove like flower shape (and lack of a terminal bud because the end of the twig dies each year thus resulting in the tree forking) got me close since princess tree, Paulownia tomentosa (Thunb.) Siebold & Zucc. ex Steud., is similar. From there I searched for just trees at increasingly higher classification levels (getting up to order) until I found it at; http://plants.usda.gov/java/profile?symbol=JAMI, where it is shown to be introduced (from South America according to Wikipedia) and thus present near where indicated.
