It quickly became the gold standard for butternut squash — prized for its reliable yields, rich nutty flavor, and exceptional long-term storage. Open-pollinated and non-GMO, Waltham Butternut has earned its place as a staple of fall gardens and kitchen tables across the country for over five decades.\u003c\/p\u003e\u003ch2\u003ePlant Profile\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDays to Maturity:\u003c\/strong\u003e 85–110 days\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFruit Size:\u003c\/strong\u003e 9–12 inches long, 3–5 lbs average\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\/Appearance:\u003c\/strong\u003e Uniform tan\/beige skin, deep orange flesh, small seed cavity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVine Spread:\u003c\/strong\u003e 10–15 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlant Type:\u003c\/strong\u003e Vigorous trailing vine\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFlavor Profile\u003c\/h2\u003e\u003cp\u003eRich, sweet, nutty flavor with a smooth, dense, deep orange flesh.
