I don't know Hebrew, but the part about it having "more logic" is a misapplication of logic. We're talking about the Garden of Eden, not the earth as we know it now. Supposedly every kind of animal and plant thrived there, so it makes no sense to talk about apples not thriving in the middle east.

The bit about leaf size is also irrelevant. As the Pook says, it's not the point of the story. Besides, there were many, many plants available, and it is not stated, or implied, that the leaves they used to cover their nakedness were from the Tree of the Knowledge of Good and Evil, anyway, because it doesn't matter. :0)
