I live in Northamptonshire and have been collecting carnivorous plants for
over ten years. I have never kept any of them outside my heated greenhouse
during the winter and in all that time I have lost one pot of two years old
Pinguicula grandiflora, due mainly to incorrect re-potting. I wouldn't dare
to keep any of my collection outside in the garden at any time of the year,
although I know of many collectors that do.

P. grandflora or P. vulgaris? The latter is hardy anywhere in the UK
(and I do mean ANYWHERE)! Also, if you are in London, you could have
quite a lot milder winters than here.
