As I have said many, many times, to everyones boredom I imagine - you can grow anything in a pot as long as you are prepared to put the work into watering, feeding and caring for it all year round I have an oak tree, several acers, and quite a few other trees and shrubs in pots, including a golden catalpa and some Japanese flowering cherries, most there for several years, all doing well. The only one which was sulking this year was the magnolia stellata, which probably wants taking out if its pot, root trimmed and fresh compost - will do it when I can find a spare pair of hands - hopefully attached to someone else.
The downside is that you really do have to keep a very close eye on them and give them plenty of atttention and care - which is why we don't go away in the summer - but with 400 plus pots in the garden I can't ask my neighbour to pop in for half an hour every two or three days to water!!! We get on well, but that might just put an end to it. I'm not suggesting everyone, or anyone, should be as daft about pots as I am, the point is that you can grow anything in a pot if it is big enough, the pot that is, and you are willing to act as mother earth for the plant.
