Cucurbita pepo 100 days. Glowing in the pumpkin patch, these bone-white pumpkins look like specters peering up through the vines. Blanco’s smooth, unblemished skin is nicely ribbed on uniform fruit for absolutely ghostly displays. Each squash measures a squat, 8 inches across and weighs 4–6 pounds. Their slender handles add an extra unusual touch with stripes of green on white. Blanco retains its pure white color better than other varieties, resisting yellowing from sunlight and frosts. Approximately 8 seeds per gram. PM.
