C. moschata. This butternut, an AAS winner in 1970, was the result of many years’ worth of patient refinement and selection by Professor Robert Young of the Massachusetts Agricultural Experiment Station in Waltham. Prized for its straight necks, rich dry yellow-orange flesh, nutty flavor, and high-yielding vines. Fruits are 3-6 pounds and exceptional keepers. One of the most popular types of baking squash. 83-100 days.
