Autumn Fruit

Today I learned that there are apple varieties that mature in mid to late November. It hadn't occurred to me that apples grew to this late in the season, but I walked past a house that had a tree in the front yard. (The apple tree that overhangs my yard tends to have dropped all of its fruit by mid-September.) I presume that it has something to do with the local climate; the general lack of frost makes for a longer growing season.
