Sugar Baby Watermelon (Citrullus lanatus) is a compact, high-yielding heirloom variety prized for its juicy, super-sweet flavor and small size, making it a favorite among gardeners with limited space. This variety matures quickly and produces icebox-sized melons (6Ð10 lbs) with deep red flesh and nearly black, matte green skin. It’s well-suited for areas with shorter growing seasons and thrives in warm weather with full sun.
