This is probably the most ancient variety of kumquat, but it’s not at the top of our list for eating. The Hong Kong, or Golden Bean, kumquat is the only kumquat that still grows wild in southern China. People flock to the hills where the Hong Kong kumquats grow whenever the fruit is in season. But this fruit is a bit of an acquired taste: the kumquats are the size of peas, the bright red-orange rind is thin, the meager pulp is bitter—and each tiny fruit contains two to four full-size kumquat seeds. And the tree protects itself with thorns. But it’s a pretty little tree.

Characteristics:

• Smallest fruit of all kumquats
• Mostly ornamental
• Dark green foliage
• Bright orange fruit
• Good for container growing
• Can train as a bonsai
• Low watering requirements
• Tiny fruits make a good drink garnish
• Grows outside best in USDA Plant Hardiness Zones 8 to 11
