I bought Autumn Beauty last year which is supposed to be a better tasting with larger fruits vs the li and Shanxi li and lang... and plus is more of a colu.nar form maybe good for pollinating some varietie the rest i have are highly rated but smaller fruits
Unfortunatley most of them send alot of suckers... from one seller did i get varieties on rootstock that did not sucker the first year though they did form basal branches.. one of them i grafted onto since the scion croaked but I think the roots are Li or Dhanzi Li or Lang the bark is reddish color... and another plant i got had no or minimal suckers... but the Autumn Beauty from a reputable place made three very thorny suckers that appear to be the Indian Jujube possibly, very thorny and that could be a mess in time
Since Autumn Beauty made so many sucker i decided best to let it grow bigger In a pot and graft onto the others ... since it's more dwarfed and also since jujubes can grow huge over time i think it would make a good top leader on other varieties to keep them smaller and the top more narrow
In another forum I posted an article discussing pollination... apparently there are two schedules... some jujubes that open and disburse pollen earlier and some later and maybe they overlap.. also there could be variances with the larger fruited or late varieties vs the smaller fruited ones that can fruit all year long , 2-3x in hitter climates ...
and so a match that will do the same is probably helpful a little but probably best to know a good match or maybe there are some that just work all around
