We bought a bunch of fruit trees from One Green World two winters ago. This year, we are getting our first crop of Red Gem Goumis.
Goumi are little fruits, and have a pit on the inside. They are slightly astringent if you eat them too early (like persimmon), but the kids really love them (far more than my husband and I like them).
Plus, goumi act as a nitrogen fixer, meaning their roots add nitrogen to the soil and fertilize the plants around them without you having to add nitrogen to the soil. Delicious permaculture!
