Just messin' with you.;-)
As a bona fide landscape professional (with a B.A. in Philosopy and a partial master's in music,) I can tell you that the samples you submitted are the fruit and foliage of an apple tree.
I don't know how tasty they are just for eating (some "yard" trees are grainy, sour, etc.) but my Grandmother had four trees in her yard that produced similar-looking apples. She made AMAZING applesauce out of them. Particularly yummy when it was hot. My mom will even make it for me sometimes with Splenda--all the yummy, none of the guilt.
Enjoy!
