I’m sorry that I don’t have any fancy Datura seeds to offer you, Jack. All I have are D. discolor, D. inoxia, & D. stramonium ‘Tatula’.
I do have a few OLD favorite Brugmansias that are finally blooming up here in the North.
Several of them are doing the “Color-Change” thing:
Miss Emily – MacKenzie Day #1 & Day #2
Jinny Lind – Day #1 & Day #2
Painted Lady – Day #1 & Day #2
