We have some friends who have a couple of them. They live in pots all year round and only get put outside during the summer months, the rest of the time, possibly as much as 9 months of the year they live in their conservatory. I get the impression that they are a bit of a labour of love and they can start to take over given half a chance and need quite a bit of pruning, which I guess means that they like the growing conditions that they have. I have never seen much flower on them, there always seems to be quite a bit of bare stem with leaves at the top.
