I have a unidentified crab apple tree with dark red crab apples. Apples are on the large side for crabs, very red flesh too. Dark pink flowers and reddish leaves in spring. Could it be Wisley crab?

Please post in the Ask A Question forum, found at the bottom left of any page.
Since you are uncertain as to the cultivar name, I will move your image into the generic apple entry.

I can't help with an ID, but those are gorgeous crab apples! We used to have a tree, and they were not as nice as those.
