If you were intrigued by Cary Fowler’s reference during his TED talk to the book “The Apples of New York,” you’ll be pleased to hear that it is online in a variety of formats. You can download it, or read it online at Google Books. Incidentally, there’s also a similar book on the pears of New York, though by a different author, “the sixth in a series of monographs on fruits, all of which have become classic references on the fruit cultivars of the period.” The pear book mentions a specific tree, the Endicott Pear Tree at Danvers, Massachusetts. That tree, which may have come to America from England on the Arbella in 1630, is still there. It is said to be the “oldest living fruit tree in North America,” although I’m pretty sure the word “exotic” should be in there too, and I do wonder about Mexico.
