Supersweet Corn

For decades, Fedco has been a firm proponent of “eating quality” in sweet corn with flavor, texture and kernel depth as our in-house metrics. We’re a “corny” flavor bunch, dismissing sweetness as the sole measure of breeding progress. Until recently, we hadn’t encountered eating excellence in a Supersweet (sh2) variety. Breeders have now balanced the extra-sweetness with tenderness, creaminess and full flavor. With the sh2 gene, conversion of sugar to starch occurs at a much slower rate, so corn stays sweet long after harvest.

Culture: Supersweet types germinate poorly in cool soils. Wait until soil temps exceed 65° for direct seeding—mid-June in central Maine.

Supersweets require 300' isolation from all other corn types to prevent the kernels of other corns from becoming starchy and tough. If you don’t have space to isolate, choosing a Supersweet means foregoing other sweet corn types.
