Jujube's are a delicious apple/date like fruit. It's also known as the Chinese Date or Korean date. They store well and are a great snack.
The taste can be compared to a crunchy apple but interestingly enough the more you chew the sweeter it tastes.
I have a Li and Lang jujube planted in ground without any protection in Seattle. The video below is the progress from flower (June) to ripe fruit (October). Enjoy!
