Someone told me it was a flowering pear tree and that it did not produce fruit, but next thing I know I see these guys on it:

There are 100s of those little things on it this year and I do not recall seeing anything like it on the tree last year. I cracked one open and it tastes like a granny smith Apple.

It has a ton of branches. I doubt it has ever been pruned in its life. In the Spring, it has white flowers.

What type of tree is this? If it can produce delicious fruit, how do I go about getting this dude to do this? If it can't produce delicious fruit, are there any grafting options that I could do? I know I'm used to Apple pies, but I'd try giving some pear pies some love too. Thank you!
