(Sh2) Supersweet Hybrids
Snappy crisp texture and ultra-sweet flavor that lasts 4-6 days in the fridge. Must separate from other non-Sh2 types by 100' or 10-14 ripening days, to prevent cross-pollination.
(SU) Normal Sugary Hybrids
The "SUs" are the modern hybrids that revolutionized sweet corn in the mid-20th century, offering high yields and fresh flavor. No isolation needed.
Heirloom Sweet Corn
Old-fashioned flavor and meaty texture. Cook within 30 minutes after picking and the taste can't be beat. Only house gardeners get flavor like this. For best flavor, isolate from other corn to prevent cross-pollination.
