The Jujube originated in China, where it has been cultivated for over 4,000 years. The fruit is round to oblong and the size of a plum with thin edible skin and white, sweet flesh. The immature fruit is green, but turns yellowish with mahogany colored spots as it ripens. At full maturity, it is completely red. The ripe Jujube looks like a date, but tastes like a sugary sweet apple. Most people like to eat the fruit at the stage when it is yellowish-green with red spots, because then it has a crisp texture. Tests have shown the Jujube to be very high in vitamin C. The trees are 20 to 40 feet tall, with branches that naturally droop to give it a graceful appearance. There are hundreds of jujube cultivars in Asia, however Willis Orchard Company offers the two most popular jujube trees for sale to add to your home orchard.
