Part of the Rutaceae flowering plant family, the Kumquat is a group of small fruit-bearing citrus trees that is notably cold-hardy. Native to the South Asia and Asia-Pacific regions, Kumquats have been an intrinsic part of Eastern culture, with the earliest historical reference appearing in Chinese literature from the 12th century.
The Kumquat tree typically grows to between 8 and 15 feet in height, with dark, glossy green leaves, dense branches that can sometimes bear small thorns. A substantial producer, Kumquats can yield hundreds or even thousands of fruits each year.
A small evergreen tree producing petite yet strongly perfumed flowers in late spring, the Nagami Kumquat has been grown commercially since 1895. Its small, oval-shaped fruit has a zesty citrus taste that is often tart, and is eaten whole (including the skin).
