Cranberries are Wisconsin’s number one fruit crop, grown on 21,000 acres across 20 counties. Wisconsin provides nearly 60 percent of the U.S. supply, and significant growth in demand is expected to continue.

A UW–Madison researcher has developed a new variety of cranberry known as “Ruby Star.” Ruby Star resulted from a cross between the “HyRed” cranberry (“Stevens” x “Ben Lear #8”) and the “Bergman” cranberry (“Early Black” x “Searles”).

Growers interested in this cranberry variety should license the variety from WARF and obtain vines from one of the approved propagators listed below. The license between WARF and the grower must be in place before vines can be obtained.

• Cranberry Creek Cranberries Inc.
• Dempze Cranberry Co.
