The calamondin is a cross between a tangerine and a kumquat, producing heavenly scent and mini oranges all year round. With its glossy green foliage and bright yellow-orange fruit, it’s a gorgeous ornamental you can grow in a container to bring inside when cold weather comes. But the fruit isn’t just a treat for the eyes. Pick these thin-skinned beauties when half ripe and let them ripen off the tree. You can use them to perk up plenty of dishes, from marmalade to Mandarin beef. Yum.
