Thanks for all the help. The ones that died almost immediately were on my covered back porch and the night time temps were in the 60's. These last ones are on my kitchen window sill. I am going to try to start a couple of the runners. the green one with hot pink flowers is doing ok so I think I'll leave that one alone for now. It's the one with the pink leaves that is concerning me. From my very limited time with them I'd have to say they are not an easy plant by any means! But I'm not giving up, I love a plant challenge!!
