I wouldn't worry. I'm in 9b, and my iochroma is just starting to come out. They like it warm, so they take awhile to start sprouting.

mantorvillain, we keep our in the greenhouse during the winter months except one that winters outside. We just moved them outside last week and they are slowly showing signs of leafing out. They are much slower then the Brugmansia and some of the colors aren't that special, I agree with you on that one.

Thanks for the feedback. They're currently out at the 'edge' of my lights in the basement (quite a while before I can move them up here in MN lol). I'll just let them decide on their own whether they want to 'play' this year.
If they do come back and the flowers are better this year what would you think of just cutting them back and carrying them over under lights next winter? The cuttings I took last fall shriveled up to matchsticks almost overnight so I don't think I'll even try to keep some..........hmmmm, anyone try their Io in the bucket o brugs setup?

mantorvillain, We have found they need the light and cuttings need bottom heat with soil. The water route didn't do a thing and the pale blue ones we did cuttings outside. I am seeing signs of leafs on a couple of cuttings but it's still to early to tell. Hope this helps in the route you decide to take.

I've tried them in water & air bubbled water. They hated both. I've found they're really sensitive to excess moisture when rooting. Straight perlite & a little bottom heat like Karma said seems to work for me.

heres how to do it. i have had great success puting cuttings in water. [ these must be large ] watch for the lenticels at on the stem if they are not present forget it. this usualy means 1/4 inch diameter. place them in a quart of water for one week. then pot them in soil in 4 inch pots and cover with plastic bags. use 24 hour 40 watt growlux bulbs. watch for roots coming out the bottom in about a week. some take longer. remove plastic and repot as soom as you see roots. i have tried bottom heat. it made no difference. i have tried bublers. this made no difference. i have tried rootone. all died. the one thing that has become very apperent in my expiriments is the size of the cutting is crucial. i have had some root in the water but this is uncomon. my success rate is 85% using the above system. somewhat lower with iocroma fuchsiodes. most begin blooming befor the roots show. my work can often be seen on ebay.

Well, its been 5 more weeks. The brugs are going great guns all over the yard and the Ios are still 'dead sticks'.
I think I'll move on. That's the nice thing bout gardening...there's always something else to try.
