Kumquat
Citrus japonica
treeKumquat trees are the smallest citrus variety, producing tiny, oval fruits with sweet skin and tart flesh eaten whole or candied. They are notably cold-hardy and ornamental, with compact growth (8–15 feet) making them ideal for container cultivation and small gardens. These trees are vigorous, disease-resistant, and can produce abundant fruit year-round in warm climates.
