I've had this white brug going on seven years but do not know the name of the variety. It was simply labeled "White Bugmansia" at the nursery from where we purchased it. Planted in the ground it reaches about 10 feet tall and about as wide.

Mary suggested in a reply to another message I posted yesterday that I post a close up view to provide a closer look at the bloom. Here are a few images. Thanks for looking.
