Silvermine grows large, heavy ears of creamy white dent corn, offering a substantial grain harvest for home milling and traditional kitchen use. The ears can reach eleven to twelve inches long and are wrapped in tight husks. This late-season heirloom needs a long stretch of warm weather for the kernels to fill and dry. Give the crop fertile ground and steady moisture, then grind the fully dried grain into meal or flour for a pantry harvest.

Large white ears for a homegrown harvest of grain.

Growing facts

  • Botanical name: Zea mays
  • Maturity or display: About 112 days to mature grain; drying may take longer
  • Mature size: Plants about 6-7 ft tall; ears can reach 11-12 in
  • Spacing: 12 in between plants; rows 36 in

About the variety

Silvermine dates to 1890 and is credited to J. A. Beagley of Sibley, Illinois. It was selected as a productive white dent corn with large ears and tight husks. Dent corn is named for the depression that develops at the kernel crown as it dries.

Starting seed

Sow 1.5 in. deep after frost in soil at least 65 F. Sprouts in 7-10 days. Thin to 12 in.; rows 36 in. Plant four or more short rows; water well through silking.

Care through the season

Choose fertile, well-drained soil in full sun. Plant several adjacent short rows to keep windblown pollen within the crop. Control weeds while plants are young and maintain moisture through tasseling, silking and kernel fill. Feed according to a soil test; do not remove healthy side shoots simply because they appear.

Harvest and use

Let husks brown and kernels become hard. Dry ears further with good airflow, then shell for meal or flour. Isolate other corn and save seed from many plants.

Saving seed

Corn readily crosses through windblown pollen. Separate varieties by adequate distance or by flowering periods that do not overlap; nearby large fields can overwhelm a small planting. Keep seed from many healthy, representative plants rather than one favorite ear to maintain diversity. Let seed ears become fully mature and dry, finish drying under cover, and label the cleaned seed with variety and year.

Common problems

Poor pollination or moisture stress can leave gaps in the ears. Watch for cutworms, corn earworms and stalk damage, and protect ripening ears from birds and wildlife. Rotate planting sites, keep the crop evenly watered, and dry harvested ears with good airflow to prevent mold.

Frequently asked questions

When is it ready?

About 112 days to mature grain; drying may take longer.

Why plant in a block?

Wind carries pollen from tassels to the silks. Several short rows together give more complete kernel set than an isolated long row.
