Ears of Double Standard corn, husks pulled back

Sweet Corn Seeds

Nothing says summer like sweet corn picked an hour before dinner. Most of our sweet corns are hybrids, sorted into sugary-enhanced (se), supersweet (sh2), and synergistic types. Supersweets hold their sugar longest after picking. Choose from Double Standard, a rare open-pollinated bicolor, Inspiration, Superb, and Natural Sweet, among others. Some are offered as treated seed for early plantings in cold soil, and several have resistance to common rust and northern corn leaf blight. Plant in blocks, not single rows, for good pollination and full ears. Pick when the silks turn brown.

Corn types and isolation

Sweet corn types differ in sweetness, texture, and how long they hold their sugar after picking. Keep supersweet types isolated from other corn by about 250 ft. or by 2 weeks of planting time, or the kernels can turn starchy. Synergistic and sugary-enhanced types are more forgiving. Check each product page for the type. Plant at least four short rows side by side rather than one long row, so wind carries pollen evenly and ears fill out to the tip.
