Green-striped cushaw, aka Tennessee Sweet Potato Cushaw squash
Though the green-striped cushaw is technically a winter squash, it also produces a spring harvest. Found throughout the American South, the 10-20 lb squash has a yellow, slightly sweet flesh that is often substituted for pumpkin in pie recipes. It has a moist, hardy nature that stands up well in sweltering summer heat. The Cushaw is a central figure to much of southwestern Native American cooking, and is also prevalent in traditional Louisiana Creole dishes. While the green-striped cushaw is not endangered per se, it tends to be grown in small batches, often for private use, and is not widely available in retail markets.
