Ziziphus jujuba 'Li'. One of the best Jujube varieties for fruit production, Li bears rounded 2 inch fruit that slowly turn from green to purple to mahogany. Seems to be most self-fertile of all varieties. These fruit-laden branches are in high demand for late summer bouquets (pair the branches in rustic Japanese jugs with copper beech, lemon clematis and bronze and green fennel). Since the small and fragrant chartreuse flowers appear after most flowering fruit trees, crops are seldom affected by late spring frosts. Trees grown in 5 gal containers, about 4' tall, 3/8" caliper as of April 2018. Zones 4-9.
