It is prized for its oval, glossy, rich green leaves and very small, round, orange fruits. The orange flesh is sour and juicy and contains a few seeds. The rind is thin, smooth, yellow-orange in color, and can be easily peeled off.

The evergreen leaves are a beautiful glossy dark green and are only 1.5 to 3 inches long. The flowers are large, about 1 inch across, and bloom in small clusters at the tips of the young branches. They are very fragrant and have a beautiful sweet scent.

Fruits are about 15 cm long and green when initially formed. They have a thin, fragrant orange rind and juicy orange flesh with few seeds when ripe. The rind is easily peeled and eaten. The fruit is very juicy and has a lemony acidity. In spring, it produces a profusion of new leaves and flowers, which may bloom every two to three months, and some trees often produce flowers and fruit at the same time.

Choose a sunny location with 6-8 hours of sunlight. Also, make sure the soil is well-drained.


After watering once or twice a week, water again when the top 2 to 3 inches of soil is completely dry. Try sticking your index finger into the soil to about 2 inches. If there is moisture, hold off watering until it feels dry at that depth. Stop watering when you see water coming out of the drainage hole at the bottom of the pot.


During the warmer spring and summer months, apply a citrus-specific fertilizer, such as the one included in the Citrus Care Kit, once every six weeks. During the fall and winter, apply fertilizer every two to three months. Be sure to follow the fertilization instructions on the fertilizer bag.
