I have a white Angel Trumpet, flowering like crazy, the other morning i noticed mid-evil spikey things forming where old blooms have dropped off, seed pods I'm guessin' - right?
OK so i went to the Brugmansia Forum to learn the plant was mis-labeled it's not Angel's Trumpet it's Devils Trumpet 2 differant plants. Angels Trumpet is a Brugmansia, Devils Trumpet is a Datura ... Also got the answer to my seed pod question
If the flowers on your plant are facing UP then you are growing Datura, not Angel Trumpets.
If the flowers are dropping down and look like a long trumpet, then they are Brugmansia or angel trumpets.
the thing you are seeing should be the seeds that are starting.
