85 Days to maturity. Cucumis melo. Ambrosia Hybrid Cantaloupe Melon Seeds. A non-GMO, annual, hybrid, heat-tolerant Cantaloupe Melon. Suitable for growing in garden plots, raised beds, and greenhouses. Resistant to Downy Mildew and Powdery Mildew. The Ambrosia cantaloupe is a large melon with a deliciously sweet flavor. The cine produces melons that have thick, peach-colored flesh with a surprisingly small seed cavity. The six-inch melons will grow best in full sun with rich, sandy soil. Ambrosia hybrid melons were bred in the U.S. as an improvement upon traditional cantaloupes, developed for better flavor and disease resistance. Ambrosia is specifically recommended by Utah State University and is favored by gardeners in that community.
