That flower could have come from either the Brugmansia or a Datura. They look the same. However, Datura, Devil's Trumpet, Jimson Weed, is about 2 foot tall, reseeds outside, and has the seed ball that is pictured, and it is highly toxic to children and pets. It's flower looks like a trumpet held up from the Devil. They will bloom in one year.
Brugmansia, Angel's Trumpet, is a tropical house plant that usually lives in a pot, gets up to 8-9 foot tall over the years, and has flowers that point down from the Angels. They do not usually get seedpods but are started from cuttings. They take a couple of years to bloom.
