The Bartlett pear is the most commonly grown variety of pear in the United States. The fruit has a bell shape, considered to be the traditional pear shape in the West. Its green skin turns yellow upon ripening, although red-skinned derivative varieties exist. It is considered a summer pear, not as tolerant of cold as some varieties. It is often eaten raw, but holds its shape well when baked. The Bartlett is a common choice for canned or other processed pear uses.
