Jujube Tree Fruit Set

I am interested in buying jujube tree seeds, but I intend to plant only one plant! What I have to know is if this jujube tree needs cross-pollination later on, to produce fruit? Can I obtain fruit with only one tree?

None of the references I consulted mentioned anything about this tree needing cross-pollination to set fruit. If it turns out that the tree needs it after all, you could always graft on a branch from another seedling (use one bud as the graft and insert it into a slit in the bark, just before growth starts in the spring, tie closed, wax the wound and hope it takes!) to get the same result as having two trees. You might want to try that anyway, because most self-fertile trees set better fruit with cross-pollination.
