Kumquat

Description

Kumquats (or cumquats in Australian English) (Citrus japonica) are a group of small fruit-bearing trees in the flowering plant family Rutaceae. They were previously classified as forming the now historical genus Fortunella, or placed within Citrus sensu lato. The edible fruit closely resembles the orange (Citrus sinensis), but it is much smaller, being approximately the size and shape of a large olive. Kumquat is a fairly cold-hardy citrus. They are slow-growing evergreen shrubs or short trees, from 2.5 to 4.5 meters (8 to 15 ft) tall, with dense branches, sometimes bearing small thorns. The leaves are dark glossy green, and the flowers are white, similar to other citrus flowers, borne singly or clustered in the leaf-axils. Depending on size, the kumquat tree can produce hundreds or even thousands of fruits each year.
