Shinseiki Asian Pear: Pyrus pyrifolia
Grows up to 12'-16' tall
 
These trees are mostly over 6 ft tall and ready to plant!
 
While online resources claim these are hardy to Zone 5, we have a couple dozen of these planted in our orchard and they have been overwintering successfully.
 
This pear's fruit is round, medium to large, and yellow smooth-skinned with little or no russet. Crisp, mild, and creamy white flesh with a hint of spice.
