Hi, I have 3 fuschias, for the first time ever. My husband bought the first one for me, and after seeing the beauty of them, and the way my hummingbirds love them, I bought 2 more. Now I am wondering if the are annuals or perennials. I am sure one is perennial, but I am looking for info on how to overwinter them. I am on Vancouver Island, Canada, and I am in zone 8.
