Mystery sapling!

[DiddlyWiddly]

Anyone guess what it is?

The underside of the leaves are the same colour and the bark to my eye looks brown/red though the photograph makes it look yellow.

There is a mature morello cherry near it, could it possibly be a baby morello?

It could be a cherry.

I thought willow at first but the leaves are too shiny.

It was very close to my morello cherry tree.
I only have the one though so I am assuming if it is a cherry it must be a wild one or a hybrid?
Though another morello would be fantastic!

I think Morellos are self fertile? That doesn't necessarily mean the resulting seed is viable, just that it can be produces without corss pollination. But if it is viable, then all three options are possible - wild (or a non-Morello garden cherry), Morello, or hybrid.

Is it’s near a cherry, I’d second the cherry guess. I’ve just cleared a couple of cherry sprouts that have popped up this week, it’s doesn’t matter how meticulous I clear dead cherries, the birds that get the highest cherries drop the ruddy pits everywhere! We’ve also had cherry runners on one side popping up from higher roots. Pain in the backside, but worth it for those cherries!

(Can’t remember what 2 types, bought in ‘98 from J Parker’s & long forgotten which 2 are grafted)!

Exciting!
The sapling was next to my morello but I also have two sweet cherry trees in the same garden and a mystery cherry in the front garden along with two kojo no mai dwarf cherries.
So lots of cherry trees!
I bet it’s a hybrid of some sort..

Are the cherries likely to be edible?
Like I won’t poison myself if it’s a wild cherry?

Wild cherries are edible, just not very juicy. They’re the ancestor of cultivated cherries
