Ziziphus jujuba. 'Lang' produces fruit that are easily mistaken for baby Bosc pears before turning their beautiful burnished mahogany. They're incredibly tasty when fully ripe, but not until then. Wait for the fruit to turn dark before eating. These fruit are also excellent if left on the tree to dry. Tree is upright and nearly thornless. Partially self-fertile, which means you can grow just one tree and get fruit, but you'll get more if you have two different varieties. Fruit ripens in early to mid-September. Grown in 5 gal containers, about 4' tall, 1/2" caliper as of September 2018.
