One of our apple trees produces these brilliantly red apples. They're red all over with no hint of green at all in their skins. The flesh is very soft and the apples go mushy quite quickly. They're also more susceptible to hungry insects. Get 'em while they're firm!
Because they rot quickly, they make one heck of a mess on the ground. The completely rotted fruit gets mushed by the lawnmower, but I have to pick up the other fruit that still has hard bits before I mow. I inevitably step (and nearly slip and fall) on the mushy apples while picking up the others.
