I just purchased the Cleo plant from this canna family which I put in a big pot for my patio. I have planted canna's before via bulb (or maybe it's a Rhizom) & have been on the internet to get an answer but can find it. I used to dig up my cannas & store for the winter (I'm zone 5 in Indianapolis). Can anyone tell me if I can overwinter this plant. Thanks, Vicki
