Oh, Karen, that's way too easy!
Actually, and I can't remember now just what plant it was, I tried that with something and the flowering stems just didn't want to root. But these are so leafy, they'll probably be fine. Gonna try it anyway; it's a pretty good sized plant. I'm just amazed that it's still going after about 3 years on my back porch!
And, oh yeah, coleus are just about the easiest thing to grow from cuttings ever! Gotta be quick to drag them back indoors in this area, tho, 'cause they really don't like the cold!
