Description

(Zea mays) Dent/Flour Corn. Despite its name, Oaxacan Green corn is an open-pollinated variety developed in Minnesota by farmer Ernest Strubbe. The long, generous ears gleam in luminous shades of green from chartreuse to emerald on six- to seven-foot stalks. For decades, Strubbe developed a rainbow of corn varieties on his farm in western Minnesota, including this green dent corn, and he was an early member of Seed Savers Exchange. Relatively early to mature, in 85 to 100 days, the plants are tough – drought tolerant and adaptable to a wide range of growing conditions. The 6- to 10-inch ears are superb in arrangements, and the kernels grind into delicious, pale green flour and meal.

Growing Guide

When to Grow

Plant Oaxacan Green corn seeds directly in the garden when soil temperatures reach about 60 degrees F, after all danger of frost is past. Depending on your local climate and USDA zone, this typically means late spring to early summer. Ensuring the soil is warm enough is crucial for successful germination​. Succession planting prolongs harvest. 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

Sow seeds 1-2 inches deep. Space the plants about 12 inches apart in rows that are 30-36 inches apart. For optimal pollination, plant corn in blocks of several short rows rather than single long rows. After sowing, keep the soil consistently moist but not waterlogged. Corn has shallow roots, so careful weeding and mulching can help protect the root system and retain moisture​.

How to Grow

As the plants grow, apply a nitrogen-rich fertilizer such as fish emulsion or blood meal to support their development. Regularly inspect for pests like corn borers and employ natural pest control methods if needed. Use row covers or erect barriers to protect against pests and wildlife. Staking the plants can help support them against strong winds. Weed control is vital; use hand-pulling, hoeing, or mulching to keep the area around the corn free of weeds​.

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.
