Thomas Jefferson documented this variety in 1790, calling it a potatoe-pumpkin when he mailed seeds to a friend. More than two centuries later it is still grown in the gardens at Monticello, and almost nowhere else. It earned its keep the hard way: an Appalachian Kentucky heirloom bred for hot, dry summers and thin patience.\u003c\/p\u003e\n\n\u003ch3\u003eWhy this squash\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVine borer resistant:\u003c\/strong\u003e a true \u003cem\u003eCucurbita moschata\u003c\/em\u003e, with the dense stems that squash vine borers rarely defeat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrought and heat tolerant:\u003c\/strong\u003e bred in the South for exactly the weather a Kansas July delivers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSweet potato flesh:\u003c\/strong\u003e tan skin over dense orange flesh that cooks like its namesake, fruits can reach 20 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeeps for months:\u003c\/strong\u003e like our other moschata varieties, cured fruits store 4 to 6 months in a cool, dry spot at 50 to 60 F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen-pollinated:\u003c\/strong\u003e save seed from your best fruit and it grows true next year\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eAbout 110 days to maturity.
