I agree with @Carol 83 . We have had one on our deck for years, they look great in flower or in fruit, which can happen year-round here. All we do is haul it inside if there's a hard freeze.
Of course, there was the one time my lawn mower (Kyle) saw a couple of fruits that had fallen off the tree and tried one. His mouth was puckered for the rest of the day.
But with enough sugar and some pectin you can make the best bitter marmalade ever. I do it a couple of times a year, even when we have a real freeze or two over the winter.
