Ziziphus jujube
In our Small Fruit Garden at the Arboretum, you will find this tree with a good sized crop of ripening fruits.  While it is an unusual plant to grow in this area, it is doing just fine.  Are you familiar with this fruit?
Excerpt from  JUJUBE: Chinese Date  "Jujube fruit is recognized as a nutritious food and important traditional medicine in China, Korea,Japan, and Southeast Asia. Jujubes are richer in vitamin C, sugar, bioflavonoids, edible cellulose, and minerals than other fruit species. Soluble solids content ranges from 20 to 40% in fresh mature fruit.  Carbohydrate content in dried jujubes can reach as high as 70 to 85%. Fresh jujube fruit contains 200 to 500 mg of vitamin C per 100 g fresh weight, while apple, pear, and peach have 1 to 8 mg/100 g fresh weight. Jujubes are also rich in cyclic adenosine monophosphate (cAMP), which is an important “second messenger” in many biological processes in the human body."
