Origins and History
Strubbe’s Blue Dent Corn is a rare heirloom variety preserved through generations of careful seed saving in Midwestern farming communities. Named for the Strubbe family who cultivated and maintained it, this dent corn reflects the deep-rooted tradition of regional seed stewardship in the United States. Like many blue corn varieties, it carries cultural significance as both a staple grain and a symbol of resilience, tying back to Indigenous and early settler traditions of growing richly pigmented maize.
Appearance and Characteristics
This variety is distinguished by tall, sturdy stalks that can reach 8–10 feet, supporting long, heavy ears. Kernels are a striking deep blue to indigo with the characteristic “dent” at maturity, giving the corn its name. The husks are well-wrapped, helping protect against pests, while the plants themselves are robust and adapted to field production. The deep coloration is not only beautiful but also indicates a higher concentration of anthocyanins, valued for their nutritional benefits. Strubbe's Blue Dent Corn is not only a visually appealing variety but also a versatile ingredient in the kitchen, making it a favorite among gardeners and chefs alike.
Culinary Uses
Strubbe’s Blue Dent Corn is primarily a grain corn, not a sweet corn, and is best suited for grinding. Its kernels produce a rich, nutty meal with a distinctive flavor perfect for cornbread, tortillas, polenta, or hominy. It can also be nixtamalized to make masa for traditional dishes, and the blue meal offers a visual and culinary uniqueness prized by chefs and bakers.
Growing Tips
This heirloom dent corn thrives in full sun and fertile, well-drained soil. It grows reliably in USDA Zones 4–9 and requires a long, warm growing season of around 100–110 days. Sow seeds directly in the field once soil temperatures reach at least 60°F. Plant kernels 1–1.5 inches deep, spacing 8–12 inches apart in rows 30–36 inches wide. For best pollination and full ears, grow in blocks of at least four rows rather than long single rows. Consistent moisture during tasseling and ear development is crucial for high yields.
The plants are tall, often reaching heights of 8 to 10 feet. They have robust stalks and large, green leaves, typical of many traditional corn varieties. Like other corn varieties, Strubbe's Blue Dent Corn requires full sun and well-drained soil. It's usually planted in late spring after the danger of frost has passed and harvested in late summer or early fall.
Harvesting Guidance
Strubbe’s Blue Dent Corn should be allowed to fully mature and dry on the stalk before harvesting. The ears are ready when husks are papery, kernels are firm, and the dent is clearly visible. After harvest, dry the ears further in a well-ventilated area before shelling. Properly stored kernels will remain viable for grinding or planting in subsequent seasons. For culinary use, grind in small batches to preserve freshness and flavor.
