Have you tried growing Lychee Tomato (Solanum sisymbriifolium)? It is also spiny like that and the “tomatoes” are pretty tasty. I think Trade Winds had seeds if you find it interesting.

Planted a couple of seeds today of Uvaria grandiflora... I have my fingers crossed!
If not for this thread I would not have known of it, so thank you very much Sahai1!

Total shot in the dark, if it isn’t strawbery guava (which seems the most likely) could it be Myrcianthes pungens?

I have three eugeniaefolia

Leaves have a faint camphorous scent when crushed.

I personally grafted a female scion onto a male carob tree. It worked exacly as I hoped with the female flowers being pollonated by the male flowers on the few branches I left in place.

Ha! That's one way to prune your trees.

This is a pretty good instuctive video on how to pollinate cherimoyas...

I grew two carob trees from seed, one turned out to be male, the other female. I grafted a different female onto the male branches, leaving one or two male branches. All that said I think there are some that are hermaphrodite.
I guess my point is that even if you end up with a male tree it may actually be a plus. You can always graft on female branches leaving one male branch... making your tree kind of self pollinating.

I have two Chinese jujubes in the ground (Li and Lang), and one in a container (Sugar Cane). That is what I am attempting to hand pollinate the Indian jujube with.

ajbb: That is interesting that the two are graft compatable, I hadn't heard that before.

Will Indian jujube (ziziphus mauritiana) pollinate Chinese jujube (ziziphus jujuba) and vice versa?

I've been attempting to hand pollinate an indian jujube seedling with pollen from three different chinese cultivars with no takes as of yet. It may be that the seedling Indian jujube is still too young or that the pollen is incompatible. I would appreciate opinions on the subject.

I have a moro blood orange that has two trunks like that, it switches sides every year. It will be loaded with fruit on one side and only have a few on the other, the next year it will be the opposite. For me this is a good thing as it is so productive that even half a tree is plenty.

My guess would be something in the cucurbit family.

Looks like a jujube
