I bought 2 daturas and received a freebie brug. It was late in the season so she decided to include it. I got 3 blooms(2 seed pods) on one datura and the others didn't bloom before it was getting cool. I decided to put them in pots(about a month) and bring them in for the winter hoping to keep them alive. The brug has dropped all leaves since I brought it in. The 2 datura have dropped some. Is this normal? Can I keep them alive over the winter indoors?
