Highlights
The charm lies in those tiny, slender cobs dressed in deep sky blue, each no longer than your thumb. Each plant generates multiple ears rather than the single cob you might expect from a miniature variety, rewarding patient gardeners with abundant harvest. Its heirloom pedigree and exceptional heat and drought tolerance make it both a decorative garden statement and a practical popcorn producer that thrives where other crops struggle.
Common Uses
Miniature Blue Corn serves dual purposes in the home garden and kitchen. The dried cobs make striking ornamental decorations, their sky blue color enduring long after harvest. The hardened kernels pop into traditional popcorn, offering a nostalgic way to enjoy homegrown corn that skips the modern hybrids and returns to tried methods of corn preparation.

Care Instructions
Direct Sow
Direct sow seeds in the garden after soil temperature reaches 60, 75°F, timing your planting for 100, 109 days before your first expected fall frost. This variety can be grown in garden plots or raised beds.
Harvesting
Allow ears to fully mature and kernels to harden completely before harvest. For popcorn use, leave ears on the stalk until the husks dry and brown, then pick and cure in a warm, dry location for several weeks. For decorative use, harvest when the cob color is fully developed and deep sky blue, and dry in a sheltered spot.
