Rosari Corn is a traditional all-purpose variety with distinctive fat, predominantly white kernels occasionally speckled with yellow, purple, or blue tones. Ears reach 8 inches in length, making them substantial enough for both fresh use and processing. This corn excels at being ground into flour for traditional preparations, though the kernels are equally suited to pozole and other heritage recipes. The variety carries the weight of Tarahumara (Rarámuri) agricultural tradition, preserved through Native Seeds/SEARCH's Seed Bank Collection for gardeners who value cultural continuity alongside homegrown abundance.

Fat, densely packed kernels distinguish Rosari from typical sweet corn, delivering a starchy substance that transforms beautifully when ground into flour. The kernel palette of predominantly white with occasional yellow, purple, and blue-white speckles creates visual interest in the field and kitchen alike. Its dual identity as both a fresh and processing corn means a single planting yields versatility, whether you're stringing together a pot of pozole or milling kernels for cornmeal that honors generations of Tarahumara cultivation.
Rosari shines when ground into flour for traditional cornmeal, a use that takes full advantage of its starchy, substantial kernels. The variety is equally at home in pozole, where whole kernels soften into tender mouthfuls while imparting a gentle corn flavor to the broth. Fresh ears can be eaten off the cob, though Rosari is better suited to these heartier preparations than to the sweet corn experience of modern hybrids.

Sow seeds directly into the garden after the last frost date, when soil temperature is at least 60 degrees Fahrenheit. Plant in rows spaced 24 to 36 inches apart, with seeds spaced 8 to 12 inches apart within the row.
Harvest ears when the husks turn dry and brown and the silks have darkened to brown or black, typically 70 to 90 days after planting depending on local conditions. Peel back the husk to check kernel maturity; kernels should be firm and fully formed but still contain some moisture for the freshest eating. For grinding or long-term storage, allow ears to fully dry on the stalk, which deepens the kernel color and makes shelling easier. Twist or cut the ear from the plant, and store in a cool, dry location before processing.
