I have this plant called datura around my mothers home, it was a mother's day present. We started with two small sprouts and they grew to almost bushlike proportions. This particular kind (there are different colors, and even a vine variety) has numerous foot long white flowers and attracted the bumblebees like crazy! Five or six bees would be on each flower everyday. The flowers last between 1 and 5 days depending on the amount of clouds, (they are nightbloomers, hence the name moonflowers) but will bloom plenty of times before the season is done. The next season the 2 plants turned into ten. They took over a patch of soil that was not growing anything and my mom loves them. Not only are the flowers beautiful, have a strange (but good) scent, and provide lots of pollen; but the spiny seed pods are my favorite part. I recommend this plant to all you bee loving gardeners looking for a late season bounty of flowers. Ive seen purple and white personally but have been told there are other colors.
What Zone?
Which zone is your mother in? I suspect these plants are not hardy here in Maryland, but they sound lovely.
Zone 5 will grow them
I'm not the original poster, but can tell you that these grow & flurish in Nebraska which is Zone 5. They reseed every year and multiply.
