I won't claim to be an expert on fuchsias, but I've got a few small plants growing in pots which I've had for a few years. One died for some unknown reason, but the others have been doing fairly well without any specialised care. I keep them in my small unheated greenhouse, but I live in a city where we don't often get winter temperatures more than a few degrees below zero celsius. The door of the greenhouse is kept open all summer, so they are almost in outdoor conditions, only they are protected from hail.
I've also successfully propagated them from cuttings by putting them in a glass of water and keeping them indoors until I pot them. There may be a better way, but I try to keep things simple unless I have a plant that I badly want to reproduce.
