Organic sweetcorn has nothing except the seed, no genetic modification, no improvement techniques, just Mother Nature at her best. Other types are: SU = standard sweetcorn, which is the sweetcorn used most for human consumption. SE = sugar extended, which is modified to be a super sweet corn. SH2 = engineered to be even sweeter than SE. Synergetic SY= combines more than one type of corn on one cob. AS = Augmented Supersweet, which has many different types of corn on one cob.
