Kumquats are adorable citrus trees with evergreen leaves, fragrant flowers, and tiny, tangy fruits reminiscent of mini oranges. They are suited to hardiness zones of 9-11, but like many citruses, they will grow happily indoors if conditions are right.
Perhaps surprisingly, kumquat fruits have edible skin (it's actually sweeter than the flesh). They can be eaten raw, candied, cooked into baked goods, or used to make marmalade. The trees, which are compact in size, are self-fertile, which means you'll only need one to enjoy a harvest.
