What is this?
Is it fruit or vegetable, it grows on a tree and the tree grows on wall.
Michigan fruits and vegetables
Can you send a picture of the outside of this?
So this is the same picture you shared before. I was interested in seeing the outside to get a better idea of the type of skin or covering. I am thinking it might be an immature paw paw which is a fruit. Hope that helps.
Thanks for your reply and yes this is the previous picture but the new picture have the outer part of it, on down right side of the picture. And for your information it's not immature paw paw. This time I don't have other picture of it but I will post you more about this, hope that will help you to recognise what is it.
Sorry but I only see the first picture you sent of the inside. You didn't mention if this was growing wild at in your home garden. Perhaps it is a cold hardy avocado which can survive in Michigan if in a sheltered area.
