OK, more information. this was growing beside the highway. It covered a medium sized tree. It was completely white with blooms. has been in bloom for 3 weeks. Obviously a hardy producer of nectar.
YOU WOULD NOT BELIEVE HOW NICE IT SMELLS - better than honeysuckle, better than Gardenia, a rose, you name it...my wife could not believe how nice it smelled. You basically have to wipe the nectar off your nose (pollen too) after sniffing it!
