I have a Lady Thumb Fuscia in a patio pot label says hardy

Same answer as the begonia question above - Crazydi has written a blog on keeping fuchsias through the winter! Good luck.

Be better if you could transfer it to the ground for the winter - this fuchsia is hardy, but all fuchsias can be sensitive to frost through their roots, so in a pot you're more likely to lose it. If you have to keep it in a pot, pot it up now into something big enough to accommodate the roots with a bit to spare, insulate it with bubblewrap or similar wrapped around the pot, stand against a wall with other pots in front of it. Prune in spring, if you need to - sometimes the stems get killed down to ground level anyway.

i have a smallish one in a pot and it goes in the unheated coldframe over winter. its other half 'tom thumb' is in the ground and comes through every april/may. well it has for the last 2 years.
