Narrative
Winkler is the largest nut of any American hazel yet found. It was selected from the wild about 1910 by Wendell Williams of Danville, Iowa. It was later introduced in 1927 by the Snyder Bros. from Center Point, Iowa. Many growers noted that this cultivar should be tried by those interested in the native hazel. Winkler is a prolific bearer of large nuts. It is hardy, at least at temperatures as low as -30 F. It is popular in the east because it is highly resistant to eastern filbert blight. Because of its traits, Winkler has been widely used as a parent in a breeding process with Corylus avellana.
