Is there anyone at Mississippi State? or at Arboretum in Picayune, MS? or anywhere?
+++ A request of help was sent to Felder Rushing and he responded with the following:
your plant is a tropical perennial named Clerodendron ugandense, commonly called blue glory bower … i am surprised it is in petal, because it usually gets killed by freezes even in the panhandle of florida. must be in a protected place or something.
I also found his website… http://www.felderrushing.net/
