US: guava fruit in Minnesota?

Okay, it's not your commonly thought of fruit for fall harvest, but guava (Psidium guajava) are very easy to grow. I keep mine in a pot in the greenhouse for the winter, but one could very easily move a guava plant indoors as a house plant, and then back outside during the warm months.

Guava is native to Mexico and Central America (I have a few growing freely at my place in Belize.) It can stand heavy pruning and still fruit—in fact it seems hard to keep them from fruiting. In Hawaii, where guava has been introduced, it grows, fruits and seeds so well that it is considered invasive. But here in Minnesota, that's the kind of forgiving tropical plant that you want, especially for beginners.

Fresh guava are not really like the jellies or canned juices that you can sometimes get in local markets. For one thing, there are not as overly sweet as those products. The flavor is subtle, mildy sweet, slightly pungent. A fresh guava melts in your mouth.
