Flint Corn
Blue Hopi corn is a striking heirloom variety treasured by the Hopi Native Americans for generations, prized for its distinctive deep blue kernels and cultural heritage. This robust annual grows 8 to 10 feet tall and reaches maturity in about 100 days, thriving in full sun and tolerating drought conditions that challenge other corn varieties. The kernels are rich in anthocyanins and deliver a mildly sweet, nutty flavor that makes them exceptional for grinding into cornmeal, crafting traditional tortillas, and preparing heritage dishes that connect gardeners directly to Hopi culinary traditions.

What sets Blue Hopi apart is its dual identity as both a striking ornamental and a powerfully flavorful grain crop. The plants tower impressively at 8 to 10 feet, creating dramatic vertical presence in any garden, while the striking blue kernels, packed with anthocyanins, compounds known for their antioxidant properties, deliver a mildly sweet, nutty taste that transforms simple cornmeal and tortillas into something genuinely special. This variety's drought tolerance makes it genuinely practical for gardeners in drier climates, a real advantage over thirsty modern corn hybrids.
Blue Hopi corn's primary purpose is as a grain for making cornmeal, both coarse meal for cooking and fine flour for baking. It's traditionally ground into flour for blue corn tortillas, a foundational element of Southwestern cuisine. The corn also excels in stews, breads, and polenta-style dishes where its mildly sweet, nutty character shines. Some gardeners save seed from their harvest to maintain the variety year after year, creating a direct link to heirloom preservation practices.
Direct sow seeds into warm soil after all danger of frost has passed and soil temperature reaches at least 60°F (ideally 70°F or warmer). Plant seeds 1 to 1.5 inches deep and space them 8 to 12 inches apart in rows 30 to 36 inches apart.
Blue Hopi reaches harvest maturity in approximately 100 days from planting. Harvest ears when the husks have dried and turned brown, and the kernels have hardened and developed their deep blue color, they should feel firm and resist denting when pressed with a fingernail. At peak maturity, you can peel back the husk to confirm the kernels have darkened completely. Cut or break ears cleanly from the stalk. For seed saving, allow ears to dry completely on the stalk before harvest if weather permits, or hang husked ears in a warm, dry location until kernels are rock-hard and easily removed from the cob.
