I took this in my yard… I have a small espaliered apple tree. It has several varieties of apple on it, but I’m not sure which varieties. This one turned red during a recent heat wave and I thought it was just sunburned. But no, it is an particularly early variety … it wasn’t until it fell from the tree that I realized it. By then, of course, the interior was mushy. (this is the first year the tree has borne fruit).
