Bred and developed by J.C. Walker at the University of Wisconsin in the 1940s, WI 55 is one of the last improved OP varieties before hybrids began to dominate the market. It’s parents include John Baer, DelMonte, Early Baltmore and Redskin.
In 2005 a Garden Web member, Martin Longseth, distributed seeds which helped to increase it’s popularity.
