We have Gravenstein, Alexander, and several kinds of Greening apples. Maybe we have a Dudley Winter or North Star, a Newtown Pippin, and an Ashmead's Kernel. Almost certainly we have a Golden Russet and a Maiden's Blush. And maybe -- just maybe -- we have a Cox's Orange Pippin, though it may be wishful thinking.
Lacking their real names, we make up names for them anyway: Fish House, Short Cut, Three Sisters.
If I pay enough attention to these apples -- their shapes and sizes, their stems, their lenticels, their streaks, their russetting and all the other wonderful aspects of apples that I never knew a thing about before last fall, I will come to know them over the years, even if I don't learn their names.
