In the early 1900s Chelsea, Iowa was famous for melons grown on the sandy hills north of town. Farmers would fill their horse-drawn “triple box” wagons in the field, haul them to town, and sell the melons right from the wagons. Today SSE member Marvin Kucera is the only person growing this watermelon in Chelsea. Sweet, pink-fleshed, 15-20 pound fruits with white seeds will keep for several weeks once picked. 80-90 days.
