The Kumquat is a native Chinese citrus fruit known for its tart-sweet flavor and small, adorable size. This cold hardy variety is ideal for cooler climates and, when potted, for small outdoor spaces.
Self-fertile with an upright growth habit and rounded canopies, kumquat trees grow tiny, white aromatic blossoms in the spring which set fruit that can be harvested typically November-April, depending on the variety.
Kumquats themselves are very small, about 1" in length and referred to as "little golden gems". You eat them, peel and all. The peel is the sweeter component and the juice is tart and sometimes sour. Most kumquats have seeds, which should not be eaten.
Like all citrus plants, Kumquat trees thrive in well-draining soil, south facing direct sun and protection from frost. They can be grown indoors with proper indoor citrus care.
There are four main species of kumquats available: The Marumi, Meiwa, Nagami and the ornamental Hong Kong Wild. In addition to these, there are many unique varieties of kumquat hybrids.

Eustis Limequats- Just as the name suggests, the Eustis Limequat is a hybrid of the Marumi kumquat and a West Indian lime. The oval fruit and thin yellow peel have a tart-sweet, acidic flavor. This ornamental tree is more cold hardy than a typical lime tree, and a good option for those who can not grow limes.
Indio mandarinquats- An ingenious cross between a Nagami and a Dancy mandarin. Its large, bell shape and bright-orange peel make this tree very beautiful as well as practical. Indio mandarinquats are a sour variety and taste best in beverages or as a marmalade.
BONUS VARIETY: Calamondin- The calamondin, or Calamansi, as it is called in the Philippines, is a kumquat - sour mandarin hybrid that is not only ornamental, but grows delicious, addictive calamondin fruit for beverages, soups and dressings. The fruit is small, round and has a unique sour flavor. The peel is not eaten unless candied, and this fruit is typically juiced. This variety also comes in a lovely, variegated variety.
