There are only 5 known species of Fortunella, endemic to moist woodlands from southern China to Malaysia. The fruits resemble miniature oranges.
Kumquats have been called "the little gems of the Citrus family".
Kumquats are slow growing evergreen shrubs or small trees that occur mainly in moist areas. They produce fragrant flowers and edible fruit. The fruit is commonly eaten raw.

Propagate from the seed in spring at 59-75°F (15-24°C). In summer, root semi-ripe cuttings using bottom heat. Semi-ripe cuttings are cuttings taken from semi-mature wood.
Evergreen shrubs or small trees, found in moist areas. Grows best with full sun exposure. In areas where Fortunella is not growing hardy, raise plants in a conservatory or cool greenhouse. Cool greenhouses have a minimum temperature of 35°F (2°C). During the day, set temperatures between 41-50°F (5-10°C), and at night, keep the temperature at 36°F (2°C). Where hardy, kumquats works well in a mixed or shrub border, in a courtyard, or as an ornamental.
Blooms fragrant, waxy, 5-petaled white flowers followed by orange-yellow, edible fruits.
Does best in moderately fertile, moist, yet well-draining soil. Soil-based potting mixes work fine for indoor plants. Water liberally during the growing season, less in winter. Top-dress or pot on in spring.
Needs moderately fertile soil to grow well. Apply a balanced liquid fertilizer monthly during the growing season.
Remove crossing or wayward shoots, annually, in late winter or early spring to maintain a healthy framework. Plants grown indoors may required extensive pruning.
Prone to spider mites, whiteflies, scale insects, citrus viruses and viroids, stem blights, leaf spots, and foot rot.
