Kumquat
Citrus japonica
treeverifiedReviewed by the GreenScout Team
Kumquat 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.
