Squaw Corn
Zea mays
vegetableSquaw corn is a colorful decorative and food corn variety with kernels in shades of blue, purple, red, and yellow. It's a flint corn type traditionally used for cornmeal, polenta, and decorative purposes. The kernels are harder and more starchy than sweet corn, making it ideal for grinding and storage.

Seedling
2-3 weeksCorn germinates quickly with the first leaf (coleoptile) emerging within 7-10 days. Young plants have narrow green leaves growing from the base.
Thin seedlings to proper spacing early. Ensure consistent soil moisture. Protect from birds and rodents if needed.
Vegetative Growth
4-6 weeksRapid leaf and stalk development with roots deepening. Plants establish multiple leaf layers and begin producing side shoots. Height increases dramatically.
Water consistently during this critical growth phase. Apply nitrogen fertilizer at V3-V4 stage (3-4 leaves visible). Mulch around plants to retain moisture and suppress weeds.
Tasseling & Silking
2-3 weeksMale flowers (tassels) form at the top of the plant; female flowers (silks) emerge from ear nodes along the stalk. Silks elongate and begin catching pollen.
This is the most critical growth stage. Maintain consistent, generous watering—stress now reduces kernel development. Avoid working among plants to prevent pollen loss. Watch for pest damage.
Kernel Development & Dough Stage
3-4 weeksPollinated silks brown and wither. Kernels develop from milky to soft dough consistency, gradually hardening and filling with starch. Kernels show distinctive color variations.
Water moderately but consistently. Allow kernels to mature fully and harden. Stop fertilizing. Watch for corn borers and other late-season pests.
Maturity & Harvest Ready
1-2 weeksKernels harden completely and develop the characteristic flint corn glaze. Husks dry and pale. Cobs turn brown. Kernels reach full color intensity—blues, purples, reds, and yellows become vibrant.
Allow corn to fully mature on the stalk for best storage and grinding. Husks can be left on for protection or removed for decoration.

Common Pests
-
Monitor for entry holes and frass (sawdust-like debris). Handpick affected ears. Encourage beneficial insects like parasitic wasps. Use Bt (Bacillus thuringiensis) spray on young plants. Remove crop residue after harvest.
-
Monitor silks for feeding damage. Apply Bt spray when silks are fresh and receptive. Use pheromone traps to monitor populations. Hand-remove affected ears.
-
Scout regularly for leaf damage and dark droppings. Remove affected leaves or plants if infestation is severe. Apply Bt or spinosad-based insecticides.
-
Handpick early in morning when beetles are sluggish. Use row covers on young plants. Apply neem oil or spinosad if infestation is heavy.
-
Remove and destroy galls before they rupture and release spores. Do not compost infected plant material. Sanitize tools between plants. Plant resistant varieties if available.

Harvest Tips
Harvest when the husks have dried and turned brown-papery, typically in late fall (September-October in most zones). The kernels should be completely hard and glossy. Snap ears off the stalk by hand or cut them. For storage and grinding, leave ears to cure on the stalk for 2-4 additional weeks after initial maturity, or hang ears in a dry location indoors. Remove kernels from the cob by hand or use a corn sheller for ease.
Fun Facts
- 🌱 Squaw corn's striking multicolored kernels are due to natural anthocyanin pigments—the same compounds that make blueberries blue and red peppers red.
- 🌱 Flint corn varieties have been cultivated for thousands of years and are ancestral to modern sweet corn; they're prized by indigenous communities for their storage quality and traditional food applications.
- 🌱 A single corn plant can produce 1-2 ears, but in optimal conditions with proper spacing and nutrition, may yield up to 3-4 harvestable ears, each containing 500-1,000 kernels.
