I like to grow sub tropicals here in the north, but time and space is limited. The Guava’s look interesting but are too big to be practical. I did find in the same family Ugni molinae or the Chilean Guava. Which is more of a bush with the fruits being berry size. Much easier to grow here. I added one this spring. So it will be some time before I know if it can work here.
I was happy this year as I got my first pomegranate harvest. Only three of them, and they were small. But they were amazing in flavor. Better than the store examples I can obtain here.
