Hi Jacob

I think this is a relatively new variety, Ive only seen it advertised in gardening mag's this year. Depending on how big it is by the end of the season, I would then decide whether to put in the workshop. I've been caught out with fushias in the past where they are labelled as hardy, but because they have not put on enough growth they didn't survive the winter
If your fushia is quite big by the end of the season it should come back no problem. They usually start to sprout about March /April time down south. They sprout from the base so just cut back the dead wood next spring.
The variety that you have, looks quite stunning in the magazines they suggest that it can climb to 2 metre's, but I haven't purchased this one ............yet!
