There are three main types of sweet corn available: Sh2, (supersweet), SUSU (normal sugary), and SESE (sugary enhancer). Sweet corn can also be classified by its color: white, yellow, or bi-colored.
Supersweet corn varieties have firm kernels and are very sweet. They are typically not as “creamy” as the other varieties. Note that supersweet corn is more susceptible than the other varieties to cross-pollination and may loose its flavor if grown too close to other non-supersweet corn crops. Normal sugary corns are creamy and sweet and very popular with gardeners. They do not store well after harvesting, and should be eaten within a couple of days. Sugary enhancer varieties have a smooth and buttery texture. For flavor, texture, and ease of growing, this is the best variety.
