C. maxima. Not well known today, these heirloom Pink Banana Jumbo pumpkin seeds have been around for over 100 years. The hard, smooth, deep-pink skin covers a solid, fiberless flesh that makes beautiful pies. Pick when less than 80cm (30") for eating, or grow to the full 75 lb size, over 120cm (48") long. This pumpkin has a vining habit, and plants get big, so provide lots of room. You'll be rewarded with two to three spectacular oddball pumpkins per plant.
