Zea mays (82 days) Open-pollinated. This rarely-offered heirloom developed by Luther Hill of Andover Township, NJ, in 1902, is one of the parents of the venerable Silver Queen. The most popular sweet corn in parts of New Jersey for more than 50 years. Sweetest OP corn I’ve ever tasted, Luther makes multiple 12-row, 3–6" long miniature ears on modest 4' stalks. Because the suckers often yield good ears, each plant, if spaced widely, can make up to four ears. A great way to introduce yourself to sweet corn the way it was before the hybrids took over. ①

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
About 85–200 seeds/oz. Seeds per packet vary.
Open-pollinated selections average 100 seeds/oz
Normal sugary varieties 140 seeds/oz
SE cultivars with shrunken seeds 150-160 seeds/oz
Days to maturity are from emergence after direct sowing; for transplants, subtract 20 days.
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.
