Thanks for the responses. I don't bring anything in, altho we did get under 35 degrees a couple times this winter. Everybody made it through that. Of course, around here 60 degrees is unbearably cold, as the one persian shield I tried told me in no uncertain terms so that's an annual.
This forum makes me want to get way more involved with the coleus. Your pics are all so tantalizing. I wanna play, too!
