Supersweet 2171 Organic Corn Seeds 4037. Thereâ€™s something new in the corn patch this year for certified organic growers. OSC introduces Supersweet 2171! This early to mid season augmented supersweet variety is a winner! Enticing bicoloured kernels in 14-16 rows are sweet, plump and juicy. The ears begin to set on very strong plants when they are only 50 cm (20â€³) high and show excellent tip fill. Short shanks on the cobs are easy snap which makes harvesting a breeze. This is the sweet corn that evens the playing field for organic growers.
