Abstract
This is a variety of Pyrus calleryana×betulifolia and has been reproduced asexually from a tree found growing in a cultivated area in Du Page County, Ill. with a growth habit of 20' wide and 25' tall without benefit of cultural pruning and trimming. When propagated by me asexually it produced straight-growing progeny with a strong central leader; a tree crown producing annually an abundance of substantially deep green leaves and flowers followed by small persistent fruit. The bark is gray-brown with reddish underbark with elongated scales broken by shallow longitudinal fissures.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinctive variety of Pyrus calleryana×betulifolia tree named `Edgewood` as shown and described herein that differs from all other varieties by the unique combination of: (1) lustrous leaves with long flattened petioles that allow leaves to flutter with the wind when other vegetation is quiet; (2) good resistance to fire blight (Erwinia amylovora); (3) transplants easily with little shock; (4) limited growth to form a well maintained, symmetrical crown; and (5) compact growth habit that requires little pruning once established; (6) reliable flower production on the entire tree, producing small pea-sized fruit; withstands flooding for a reasonable period of time.
