Unwrapping a husk of Glass Gem corn is like looking at a beautiful stained glass window, with all the translucent colors of a rainbow.

  • Developed by Carl Barnes, a part-Cherokee farmer/breeder from Oklahoma, over many years of selecting the most wild translucent kernels.
  • Not just an ornamental, but also good for popping and grinding into cornmeal.

SPECIFICS: (see below for complete sowing information)

  • SEED DEPTH: 1 1/2 inches
  • SEED SPACING: 5-8 inches apart in 4 foot x 4 foot blocks or rows 24 inches apart
  • EMERGES: 8-15 days
  • MATURES: 60 days


  • Plant corn seed in full sun directly in the garden when the soil has warmed to at least 70-degrees and night-time temps do not dip below 60-degrees.
  • Corn requires full sun and fertile soil and abundant water.
  • Plant seed 1 1/2 inches deep, 5-8 inches apart in blocks (4 foot x 4 foot) or rows 24 inches apart.


    • Germinated in 8-15 days depending on soil and weather conditions.


    • Glass Gem produces numerous side stalks (called tillers) and each will produce 1-3 ears.
    • Corn is wind pollinated and crowded plants may not produce full ears.
    • Thin as needed to allow air circulation between plants (averages 12 inches apart).


    • Corn is a heavy feeder; plan to fertilize 2-3 times during the growing season by mounding compost around the crown.
    • Pick when the entire plant has dried to a golden brown.
    • Dry ears completely to use as popcorn or to grind into cornmeal.
