While it may appear the only thing I have blooming right now are Angel Trumpets, that is hardly the case.  Because of my hybridizing efforts I just pay more attention to my brugmansia than other things in my yard.  My favorite late season flowering tree is the Silk Floss tree. It started blooming about 6 weeks ago and will continue on for another 3-4 weeks.  The blooms are large and colorful, and the trunk has giant spikes, making this tree a real eye catcher.
