Description

(Zea mays). A super high-protein dent corn with phenomenal flavor and blazing color! Bronze orange was shown to contain 50 percent more protein than standard GMO corn samples in a study conducted by Baker Creek. The beta-carotene in orange-colored corn has recently been recognized as a tool to fight nutrient deficiency-related childhood blindness and vision problems. Dwarf stalks are only 3 1/2 feet high. Despite its small stature, it produces up to 5 ears per stalk! Makes choice roasting ears at the milk stage (although not exactly a sweet corn), or allow the burnt-orange kernels to develop completely for a superior flour type. Originally introduced by Dr. Alan Kapuler in the 1980s.

Growing Tips: Bronze Orange corn, an eye-catching heirloom variety prized for its glowing bronze kernels, thrives in full sun and nutrient-rich, well-drained soil. Corn is a heavy feeder, so amend the soil generously with compost or aged manure before planting. Ensure steady moisture during tasseling and silking to support kernel development. Plant in blocks of short rows for effective pollination and uniform ear production.

When to Grow

Sow Bronze Orange corn after the last frost date when soil temperatures reach at least 60°F. This warm-season crop requires a frost-free growing window of 90–110 days for best results. In cooler climates, start with black plastic mulch to warm the soil. 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 seeds 1–2 inches deep in fertile, well-prepared soil. Space plants 8–12 inches apart in rows 30–36 inches apart. For optimal pollination, plant in blocks of four or more short rows rather than a single long row. Keep soil evenly moist until germination, which occurs in about a week. Thin seedlings if overcrowded to maintain airflow and healthy growth.

How to Grow

Provide consistent watering, especially during flowering and ear development, as drought stress can lead to poor pollination and small ears. Side-dress with compost or organic fertilizer when plants reach knee height. Weed carefully to avoid disturbing shallow roots. For flour corn, harvest ears when husks turn brown and silks are dry. Bronze Orange corn can be used for fresh eating, roasting, or ornamental displays.

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.

FAQ

Can I grow Bronze Orange corn in a small garden?

Yes, but plant it in blocks of at least four rows to ensure proper pollination. Single rows often lead to uneven kernel development and smaller ears.

When should I harvest Bronze Orange corn?

Harvest when the silks have dried and turned brown, and kernels feel firm. For dry corn, leave ears on the stalks until husks are papery and kernels are hard.

Does Bronze Orange corn need fertilization during growth?

Yes. Corn is a heavy feeder—apply compost or organic fertilizer when seedlings reach knee height and again during tassel formation for strong stalks and full ears.

What gardeners are saying

  • Short season: Fast enough to crop in short northern summers.

  • Flour and masa corn: Metallic bronze kernels, grown for flour, masa and baking.

  • Good yields: Stalks to 6 feet with 2 to 3 ears each, a large crop to freeze.

  • Drought tolerant: Grew well with little water, from a desert garden to Alberta.

  • Heads up: Ants and corn earworm got into some ears; check them as they fill.
