Rarámuri Maiz Caliente is a striking corn variety grown by the Rarámuri people of Mexico's lower canyons, prized for its tall stature and distinctive apricot to copper-colored kernels. Named for the hottest time of year when the Rarámuri plant it, this heirloom thrives in zones 3 through 11 and germinates in warmth between 60 and 75 degrees Fahrenheit. The long ears and small kernels represent generations of adaptation to canyon growing conditions, making this a living link to Indigenous agricultural knowledge.

The Rarámuri call this corn 'caliente' because they plant it when summer heat peaks, a timing that shaped the variety's entire character. Tall plants bearing impressively long ears filled with small kernels in warm apricot and copper tones, it's a visual and cultural standout that brings authentic southwestern heritage into any garden. Preserved through Native Seeds/SEARCH's Seed Bank Collection, growing this corn connects you to centuries of Rarámuri farming tradition.
As a grain corn, Rarámuri Maiz Caliente is used for traditional food preparation, including grinding into flour for tortillas, atole, and other staple dishes central to Rarámuri cuisine. The small kernels and distinctive flavor make it valuable for both fresh harvest applications and storage as a dried grain for year-round use.

You can start seeds indoors in warm conditions 3 to 4 weeks before your last frost date, keeping soil temperature between 60 and 75 degrees Fahrenheit. Sow one seed per cell at the depth specified below, and transplant once plants reach 4 to 6 inches tall and all frost danger has passed.
Transplant seedlings outdoors only after your last frost date has passed and soil has warmed to at least 60 degrees Fahrenheit. Harden off plants gradually over 7 to 10 days, reducing protection from wind and direct sun each day. Space transplants 8 to 12 inches apart in rows 30 to 36 inches apart.
Direct sow seeds outdoors after the last frost date and when soil has warmed to at least 60 degrees Fahrenheit. Plant when nighttime temperatures reliably stay above 50 degrees and daytime heat is strong, reflecting the 'caliente' timing the Rarámuri use.
For fresh corn, harvest when ears are in the milk stage, which typically occurs 60 to 80 days after planting; the kernels should be plump and milky when pressed. For dried corn, allow ears to remain on the plant until the husks turn brown and papery and the kernels have hardened completely. Strip ears from the stalk and store in a cool, dry place to finish drying if needed before shelling.
