Hopi Turquoise corn carries the agricultural legacy of the Hopi people, a variety shaped by thousands of years of cultivation in the American Southwest. This tall annual grass grows 48 to 72 inches high and produces edible ears with the distinctive turquoise-blue kernels that give it its name. Hardy across zones 2 through 11, it thrives in full sun and moderate moisture, offering gardeners a connection to indigenous farming traditions while delivering a genuine vegetable harvest.

The kernels display that striking turquoise-blue color that makes this variety instantly recognizable in any garden, a trait preserved through generations of Hopi seed saving. As a wind-pollinated crop, it requires community in the garden; plant it in clusters of at least a dozen plants arranged in a square or circular pattern to ensure robust pollination and heavy yields. The variety's hardiness across such a wide range of zones means gardeners from cold climates to warm regions can grow it successfully.
Hopi Turquoise corn can be eaten fresh off the cob as sweet corn, though it is also well suited to drying for storage, grinding into cornmeal, or use in traditional preparations. The dried kernels can be popped like popcorn, echoing the popping ability of its wild ancestor teosinte, or ground into flour for breads and other staples.
No timeline data available yet for this variety.
Direct sow seeds into warm soil (minimum 60 degrees Fahrenheit) in full sun once all danger of frost has passed and soil has warmed thoroughly.
Harvest ears when kernels are full and plump, typically in mid to late summer during the growing season. For fresh eating, pick ears when silks have turned brown and kernels release a milky liquid when pierced. For drying and storage, allow ears to mature fully on the stalk until the husks dry and papery; kernels should be hard and fully dented at the crown before harvesting for grinding or popping.

“Modern corn descended from teosinte, a wild grass native to Southern Mexico that ancestors began selecting and cultivating between 13,000 and 6,000 BC. Archeological evidence from Southern Mexico reveals maize cobs radiocarbon dated to around 5,000 BC that already showed intermediate features between wild teosinte and domesticated corn, proving how deliberate and sophisticated early farmers' selection work was. The Hopi people of the American Southwest continued this tradition of careful seed selection for centuries, developing varieties like this turquoise corn to thrive in their specific climate and to meet both culinary and ceremonial needs. Teosinte's ability to pop like modern popcorn and its genetic compatibility with corn underscore the fundamental similarities between ancestor and descendant, a living connection to ancient agricultural wisdom.”
