Description

(Zea mays) Flint Corn. A stunningly beautiful corn from the great Osage people! Six- to 7-inch-long ears bear rounded, solid kernels that come in a myriad of combinations: blue-black speckled with white, white speckled with blue, orange speckled with blue, or orange speckled with black. It is perfect for grinding into flour and meal. This variety is endangered and hard to find.

Growing Tips: Big Horse Spotted corn thrives in full sun and well-drained soil. This hardy, open-pollinated variety is best suited for growing conditions that support a consistent moisture level. The corn grows to about 4-6 feet tall, with each stalk producing two ears measuring 4-6 inches in length. It performs well in regions with slightly acidic to neutral soil (pH 5.8-6.2) and benefits from moderate watering, especially during key growth phases like silking and grain filling.

When to Grow

Plant Big Horse Spotted corn when soil temperatures reach about 60 degrees F, after all danger of frost is past. This variety requires warm soil to germinate, so ensure soil temperatures are consistently above 50 F. The best temperature for growing is 75-80 F. This variety is ideal to start planting in late spring to early summer. For optimal results, avoid planting too early in cold soil to prevent poor germination​​.

How to Sow and Plant

Sow seeds 1-2 inches deep, spacing them about 12 inches apart within rows that are 36 inches apart. Planting in blocks of at least four rows ensures good pollination and well-filled ears. The seeds should germinate within 7-10 days if the soil temperature is right. Thin seedlings to the strongest plants once they reach 4-6 inches tall​​. Succession planting prolongs harvest.

How to Grow

Maintain a consistent watering schedule, focusing on watering the soil directly rather than the foliage to prevent diseases. Mulch around the base of the plants to retain moisture and suppress weeds. This variety is fairly hardy but thrives with regular weeding and monitoring for pests. The corn reaches maturity in about 75-95 days​​.

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.
