Wisconsin 55

Tomato

Solanum lycopersicum

Overview
Produces 6-8 oz. slicers that are great for fresh eating and popular for canning, particularly for stewed tomatoes. This long-popular workhorse variety was developed by the University of Wisconsin, Madison in the 1940's. While there are several strains of Wisconsin 55 on the market, their quality has degraded over time. That is why Johnny's identified this strain, which shows more consistent size, healthier plants, and fewer fruit defects than other commercially available Wisconsin 55 strains. We also believe ours to be closer to the original variety. We acquired it from University of Wisconsin, Madison plant geneticist Ted Bingham, who had frozen Wisconsin 55 seeds purchased in the 1960's. Demonstrates some field tolerance to early blight and Septoria diseases. Indeterminate.
