Kumquat (Fortunella species)

The kumquat is an ornamental shrub or small tree from China.
The trees, bushy and symmetrical with orange yellow fruits, are highly prized as ornamental tubbed plants for open lanais or pool decks.
Two major varieties are grown in Hawaii.
The Nagami kumquat is known for its oval, brightly colored orange fruits.
The Nagami fruits are valued for marmalades, preserves, dried fruits, and for decorative purposes. The Meiwa kumquat is known for its large round fruits.
Its thick, sweet rind and comparatively sweet flesh make this variety the best kumquat for eating fresh.
