Supersweet (sh2)
Supersweet or shrunken-2 types have four to ten times the sugar content of normal sugar (su) types and with proper handling is able to be stored for up to 10 days. Less hardy than even se types, requiring higher germination temperatures, precise planting depth and isolation from all other corn pollen for optimum results. The name derives from the shrunken, shriveled appearance of the dried kernel which is low in starch.
