Erwin's Delight - Information from donor Arnold Tschanz:Erwin Tschanz is my father. The tree is located in Rochester, NY and was probably 30-40 years when we moved into the house back in the early 1950s. My brother Ernest had found a few trees in an orchard in Webster, NY that had fruit that was very similar. The fruit looks similar to the one type of Asian pear that has a roundish shape with russet skin and a bright green under layer. A winter ripening pear.
