I have never seen anything like this! Our ornamental crabapple tree is blooming, in September! The only thing we can come up with is either the bad July hailstorm traumatized it, or the extra hot late summer weather. Pretty cool, though!
Proof that it's on the same tree with the ripening apples.
I tried to get my camera set so the date stamp would be on the picture but I failed. You'll just have to take my word that it's blooming on September 5, 2013!
