Some very generous folks sent me some datura seedlings and seeds this year. So far the seedlings are about10" tall, do you think they will bloom? The ones from seeds are about 3" tall, any hope for them? I have them planted in galvanized buckets and would like to know how I can save them through the winter in zone 6? Any suggestions for this curious newbie? Thanks
Zinnia: Which kind of daturas are you growing. I have overwintered datura innoxia in a greenhouse. It now has woody stems and blooms profusely. I have also overwintered datura double purple. It is about 5 feet tall and covered in blooms for a second year. ( seeds from Thompson and Morgan, sold as brugmansia x candida black current swirl) It is definitely not a brug but absolutely beautiful.
I have a picture of a datura on the photo forum (although it looks like a brug 'cause it is hanging down). I didn't do anything to mine but clear away the dead stems when they died back. This is my first year with datura and brugs so we will see.
Zinnia-No,I didn't cut it back but maybe I should have.I watered it only enough to keep it from drying out. But remember , you are in zone 6 and I am in 8. I have a double purple that I think I will try to over-winter this time,as well as save seeds. I have Innoxia, Torna Loco and a Brugmansia that are on their own for next year.
D. innoxia is reliably root-hardy throughout Zone 7, and I've talked to several people who have it coming back from the root in Zone 6. If you want to take yours inside, I'd suggest you don't try to keep it from going dormant---this seems to sort of 'recharge' the batteries for next year's growth. Keep above freezing, with good but indirect light, and water sparingly. Increase both water and light around late March, and give her room!
