Citrus japonica, commonly known as kumquat, is a small, evergreen tree native to southern and eastern Asia. The first record of this plant is in Chinese literature from the 12th century C.E. Thin, dense branches bear dark green, glossy, elliptic foliage (up to 2" long and 1" wide). The branches, especially new growth, may also have thorns. In late spring, fragrant white flowers bloom singly or in clusters from the leaf axils. The orange fruits are round to oval in shape and small (less than 1" in diameter). 'Centennial Variegated' is a compact kumquat selection that features white and green variegated foliage as well as variegated fruit. The fruits (around 1.5" in diameter) have a smooth, thin rind with green and yellow streaks when immature and orange to red streaks once ripe. They have a strong citrus aroma with a sweet and tart taste. This variety is also essentially thornless.
