Further datura observation - I stand corrected! I think I said the scent at night was heavenly and that you wouldn't smell it during the day. I was wrong on two points. (You can see the flowers beginning to collapse.)

1. The smell isn't heavenly.
2. You can smell it during the day, I guess as long as the flowers are open. I could smell these this morning from at least three feet away - still looking to attract moths?
