Incredible R/M Corn
Incredible R/M Corn is a hybrid sweet corn bred for reliable performance across a wide range of growing conditions, from zone 2 through zone 13. The plants reach 72 to 84 inches tall and produce long yellow ears measuring 8 to 9 inches, packed with 14 to 18 kernel rows. Maturing in 85 days, this variety tolerates heat and drought stress better than many sweet corn hybrids, making it a dependable choice for gardeners in challenging climates. Its standout feature is exceptional holding ability, meaning the kernels stay tender and sweet on the stalk longer than typical corn varieties.

Highlights
These long, bright yellow ears stay sweet and tender on the plant far longer than standard sweet corn, a trait that gives home gardeners real flexibility at harvest time. The plants reach moderate height (72 to 84 inches) and thrive in heat and dry conditions where other corn struggles. Resistance to common corn diseases, including Common Rust, Maize Dwarf Mosaic Virus, Northern Corn Leaf Blight, Southern Corn Leaf Blight, and Stewart's Wilt, means you're growing a variety bred to handle what nature throws at it.
Common Uses
Incredible R/M Corn is grown for fresh eating straight from the cob, the extended holding ability means you can pick ears at peak ripeness over several days rather than rushing to harvest all at once. The sweet kernels work beautifully in corn salads, grilled whole, or cut from the cob for side dishes and soups. Home gardeners prize it for its reliability and the flexibility its holding power provides in the kitchen.

Care Instructions
Direct Sow
Direct sow seed outdoors when soil temperature reaches 60°F or warmer, planting seed 10 inches apart in rows 36 inches wide at a depth of 1 to 1.5 inches. Sow 1 to 2 weeks after your last spring frost date for best results.
Harvesting
Pick ears when the husks are bright green and tightly wrapped around full, plump cobs. Kernels should be full and milky when you pierce them with a fingernail, with silks turning dry and brown. The exceptional holding ability of this variety means ears remain in peak condition for several days after reaching maturity, giving you a harvest window of roughly 80 to 89 days from planting. Twist or snap ears cleanly from the stalk, leaving the stem intact.
