Kumquat (Fortunella spp.)

Kumquat trees are small, slow-growing evergreen citrus trees that reach a mature height of 10 to 15 feet. The leaves are simple, alternate, and one to three inches long. They are dark green on the top of the leaf and lighter below. The flowers are pure white. Kumquats are the smallest citrus fruit. There are several species which vary widely in size, shape, and flavor. The fruit is oblong or round in shape and orange or reddish-orange in color. The rind is thin and pebbly. The flesh is in three to five segments, lacking in juice, with rather large seeds for the size of the fruit. Fruit may be tart or sweet, depending on species. Kumquats can be grown throughout Florida and are widely used as ornamental landscape plants.
