This other tree sprouted from the same space as the hardy apricot. It has such un remarkable leaves that it is hard to find what it could be, but the new growth is reddish and it is woody starting about 2 or 3 inches from the tip of the new growth. I have found some pawpaw seedlings that look similar but i am not really familiar with them.

I'm not sure of your location but it looks a aweful lot like a guava I have growing in my greenhouse.

It looks like persimmon to me.

Hey scott and Akiva thank you for the suggestions. I always have trouble with simple leaves and identification.
I guess if it is guava or some other tropical plant than i will know when it dies off over the winter. If it is a persimmon than it must be sent from the heavens, because that is one of the fruit trees that were originally on my land and one i am interested in growing.

The hardy apricot is in full shock mode from being transplanted so i am concerned about it not even making it through the winter. I am glad this mystery tree has the potential to fill the void if the apricot does not return.

real hard to tell when young, hopefully once it gets bigger it will get clearer.

it also looks a lot like persimmon to me.
