I have two mystery fruit trees on our farm. We have had this property eight years and every year these trees are prolific fruit producers, though only the wildlife are benefitting. Finally this year I decided to really try to identify them and they look like Jujube. Is that possible here in Gatesville? No extra water or fertilizer, but hundreds of fruits that taste like and look like a dry apple with a pit in the middle. Green fruit is the size of my thumb, and darkens reddish and shrivels over time. Leaf has three veins and waxy/shiny on front side. Thank you!

It is possible and the picture looks like jujube to me.
