The foliage is another trait that LaFleur and Churchpoint share. Today, I noticed that the LaFleur graft on a So (at a rental) looks much greener than the rest of the tree. I went back and found this post from 2021, where I noticed the same thing about a Churchpoint graft on a So at my house.
It doesn’t prove that they are the same- though maybe it is evidence that they are at least related in some way, even if it is the class of jujube (eg wild-type).
I checked Prof Yao’s Genetic paper and it has Churchpoint, but not LaFleur, so no help from that perspective.
I picked another jujube for the first time today, Cliff’s Big Sour, the two middle fruit in this pic. This one is the 2nd tartest jujube I’ve had. Texas Tart has it beaten on that front. But, while I can only eat a few of the eye-wateringly sour Texas Tart, I think I would be fine with more of CBS. Similar to TT, the texture isn’t ideal. It may be a bit crunchier, though I think it is a bit drier as well. Size is about the same as Honey Jar, so slightly bigger than Texas Tart. So Cliff’s Big Sour is big for a wild jujube, but on the small end for most cultivars.
One thing that is big for CBS is the pit. Here are the two pits next to half a Honey Jar. I saved them for later planting. It wouldn’t surprise me if each pit had two seeds (as Texas Tart often does as well), given the size of the pit.
Here’s a pic of one way I keep the size of my trees down. When they get tall enough that I can’t reach the fruit from a 8’ ladder, I cut it where I can reach and pick the fruit from the ground. I had my dad (who was picking some jujubes) take the pic of me with the branch, before I picked 1.3 pounds of fruit (plus a few seconds) off it.
Note that I picked a lot from this Sugar Cane tree 3-4 weeks ago. This branch was new growth, with a 2nd flush of fruit.
