Description

(Zea mays) Flour/Dent Corn. Truly breathtaking blue corn said to originate from the Hopi people of the Southwest. This variety yields lovely ears with colors ranging from slate blue to brilliant turquoise with some surprise purples. Used locally in atole and ground for cornmeal, kernels are both flour and dent types, both often bearing on the same ear. Ears typically run 6 to 12 inches long, and are produced usually one per 4-to 5-foot stalk. It has grown well even at 8,000 feet elevation, indicating tolerance to wide temperature swings and cool soil. Fairly early to mature, it is ready for harvest at about 90 days from sowing. Our grower received his original seed in 1986 from John "Eesawu" Kimmey, an educator and visionary of sustainable Native agriculture who worked extensively with the Hopi people and founded the Talavaya Center, an early heirloom conservation project.

Growing Tips: For optimal growth, plant the seeds in full sun in well-drained, fertile soil. Regular watering is essential, especially during dry periods. Mulching can help retain soil moisture and control weeds. Given that corn is wind-pollinated, plant the seeds in blocks or multiple rows rather than a single line to ensure good pollination.

When to Grow

This corn variety should be planted in late spring, when soil temperatures reach about 60 degrees F, after all danger of frost is past. In most U.S. zones, this corresponds to late April through June. You can check your local frost dates to determine the best planting time​. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Direct sow the seeds in your garden, planting them 1-2 inches deep and 12 inches apart. Space the rows 30-36 inches apart. Given that heirloom varieties can sometimes have lower germination rates, consider starting some seeds in trays to fill in any gaps later. Germination usually occurs within 7-10 days. Plant in blocks for effective pollination and a higher yield​​. Succession planting prolongs harvest.

How to Grow

Once planted, ensure the corn receives adequate water, particularly during dry spells. Use well-rotted compost or a balanced organic fertilizer before planting to enrich the soil. As the corn grows, side-dress with a nitrogen-rich fertilizer to support robust growth and ear development. Be vigilant against pests like corn borers and earworms by using organic pest control methods. Regular weeding and the application of mulch can help manage weeds without disturbing the roots​​.

How to Save Seeds

  • Corn is wind pollinated and will easily cross with other varieties (including GMO corn!). You will need at least 1 mile of isolation to avoid cross pollination. You can also use staggered timing or caging techniques.
  • Hand pick ears when fully dried on stalk. Seeds keep best if left on the ear; just remove at planting time.
  • Sweet corn seeds will remain viable for 2 years; dent corn will last up to 5 years when properly stored.
