I purchased some dehulled Jujube seed from Foxgreen Farm / https://jiovi.com In July 2018 (about a year ago) which I planted almost immediately into a tray in the greenhouse.
Being located in New Zealand, this was mid winter.
Germination rate was about 50%, pretty good by my experience with imported seed and the feedback from other growers.
A year on I have about half left alive, about 20 - 30cm tall in 3 litre pots (do the math imperialists, see how you like it...)
Of these about half are single stem and the rest are multi branching from ground level, there is obvious variation in leaf shape and colour
Having attempted and lost purchased Jujube trees in the past, growing from seed seemed like it would improve my chances at lower cost.
I'm tempted to plant mine out this coming spring but the destination location is rather harsh and out of site / mind and I'm afraid they might get a little neglected and then swamped by weeds so I'll probably wait another year. Or do half soon but in a closer and more monitored location....
Having never even tasted a Jujube I have no fixed expectations about what I might get out of all this.
