Grow Bougainvillea here in the UK that is, I have managed the odd 2 or 3 year stretch but they normally do so poorly that you end up feeling guilty for torturing the poor thing
Out doors in Cornwall I think we are more limited by cool summers than by winter minima for these. Even on a south facing wall they don't seem to 'ripen' here.
I am trying to remember where I saw one in London, but have a feeling it was in some ones very posh fruit greenhouse up again a very sunny south facing wall under glass. If it is the one I am thinking of a section of it goes outside continuing along the same wall and is constantly looking tatty.

I knew I had seen it somewhere, although I think I have got my plants confused, as the one I mentioned in my original post is not Waynes :lol:
Dave Bindon grew and flowered a Bougainvillea successfully for several years on a sunny wall when he lived in North London, but I don't suppose it's a great challenge now that he's living in Athens...
A major plant in my garden and I couldnt imagine not having one.
I cant grow them in the ground but they are quite happy in pots and winter easily in the greenhouse.
My biggest plants are B.glabra, the darker purple ones and I think the hardiest of them all.
I leave them in the greenhouse until the bracts are forming then bring them out for summer where they flower (well bract) for the most of it.
Also in pots I can move them about to give a mass of colour where its needed.
I keep these on a cane wigwam and keep them pruned back to 6 or 7 foot.
I have a variegated B.'raspberry ice' in the conservatory and although still a young plant 93 years old now) it has kept and produced several brachts all through the winter.
I think this one is my favourite and as it easily handles hard pruning it can come inside for winter for many years to come.
