different kinds of pear trees
The Asian pear tree is best known for its long-lasting fruit. Unlike other varieties of pears, the fruit of the Asian pear tree can be eaten as soon as it is picked or months after it comes off the tree--as long as it's kept cold.
The Bradford pear is another ornamental pear tree, and a fairly recent addition to Western agriculture. Originally from China and Korea, the Bradford pear is not well-suited to colder climates because of a vulnerability to not just cold damage but to breaking from wind and the weight of snow and ice.
