it could be.

yes, definatly

Edible, yes. Tasty? Can't say. Best way to tell is by taking a bite. If yours is from a grafted tree that someone planted, it is most likely quite good tasting. Almost all apples sold in markets come from grafted trees.

If yours is from a tree that grew from a seed it could be tasty or could be rather so-so. Only way to really know is by eating it. That is how new varieties are often found.

Thanks everyone. I am just surprised by how tiny these apples are. I did taste one and it really has very little apple taste to it. I feel like I am "eating the young"...
