Types of sweet corn
Normal Sugary (su): standard varieties with traditional sweet corn texture & flavor. Sugar converts to starch quickly, so eat them within a few days. Tend to have high yields and germinate well in cool soils.
Sugary Enhanced (se): more sugar than su, tender kernels & slightly longer storage time. The * indicates heterozygous (only one parent contributes the se gene); all others are homozygous (both parents se).
Supersweet (sh2): 4 to 10 times the sugar content of su and se. Conversion of sugar to starch occurs at a much slower rate. Stays sweet long after harvest. Extra shriveled seed does not germinate well in cool soil.
Synergistic: more sugar than se. Very tender with long harvest and storage windows. Can be homozygous or heterozygous se with added sh2 kernels.
TripleSweet® Sugary Enhanced: has homozygous se kernels, and 25% of these also contain the sh2 trait.
Corn
Culture: Untreated sweet corn seed will not germinate in cold wet soil. Please be patient and wait till soil warms to at least 60° before sowing, or start seedlings indoors and transplant at 3–6" before taproots take off. Minimum soil temperature 55°, optimal temperature range 65–85°. Tender, will not survive frost. Heavy nitrogen requirements.
