Other than 'Thai Giant', what other varieties are available in the US?

I have some Taiwanese Jujube cultivars. They are hard to come by and I think most in the US have not eaten a true Taiwanese jujube cultivar like on the image (including me). I believe Shirley 13 and Alian 16 are some of the crispiest and newest varieties...and sweetest, like 18 brix. There isnt a real solid way to identify them so you have to trust who you buy them from. Theres many people selling some of these cultivars and its highly suspected they are not the variety they claim. One thing I've learned to look for in most of the newer Taiwanese jujube cultivars is large, wide, almost round, wavy leaves. Interestingly the Thai jujube is more well known than the Taiwanese jujube but the Thai jujube is really just an older variety imported Taiwanese jujube. Taiwan is by far the leader in jujube (Ziziphus m.) quality breeding. Would be interested in hearing a taste report from anyone who's tried one of the varieties on the attached image.
Kankan, thank you for this info. Now I have a better starting point to try to find some of these varieties.
Where did you source your cultivars? Are your trees fruiting yet?
