I think either the Taiwan jujube is a type of Indian jujube, or it is actually just a name for Indian jujube when sold by Taiwanese nurseries.
Is Indian jujube expensive? Taiwanese jujube is actually pretty pricey.
My mom and a couple of friends grow the Taiwanese jujube. Friends get good amount of fruit set, my mom not so much, but the plant gets pretty big when it's not setting fruits.
