No other early yellow corn combines a large 9" ear and great cool-soil vigor with Sh2 sweetness. Plant corn in blocks at least four rows wide for cross-pollination and well-filled ears. Plants grow to 5' high. For the best flavor, isolate Northern Xtra-Sweet from non-Sh varieties to stop cross-pollination. A packet contains 200 seeds, enough to plant four 15 ft. rows. Seeds are not treated.
