I'm a new to this site and also new to gardening. My husband bought me a HUGE variety of flowers this past May so I can start a garden. All my flowers have done extremly well but I am afraid of our winters here in the Midwest. I live in Moline, Illinois and our winters can be pretty harsh. Here are a few flowers that I have no idea what to do to prepare them for the winter:
Luna Hibiscus
Hydrangea
Hollyhock
Verbena

If anyone can please give me any suggestions I would very much appreciate it. There are way too many websites and they all say one thing or another...HELP!
