Seminole XR Sweet Corn


A Hoss Favorite! Seminole XR Sweet Corn is a supersweet (sh2), bi-color hybrid with tender, flavorful, and very sweet kernels. Plants produce large, 7″- 8″ ears that are filled to the tip and plants typically reach 6′ – 6.5′ on average. We trialed this variety in several growing zones across the United States and performed well everywhere it was grown. It’s widely adaptable and able to handle different soil types and conditions. Seminole XR has an incredibly sturdy plant and ease of pick when ready to harvest. The harvest window on this variety seems to be quite longer than other sweet con varieties, from at least 10 days up to 2 weeks in some cases. A great roadside, market variety! Zea mays. 80 days to maturity.



Check out our Corn Growing Guide to learn more about how to grow corn in your garden.

Sweet corn should be planted in the spring after the last frost date. Sweet corn can be grown throughout the warmer months up until fall, as long as time is permitted for harvest before first frost. Succession planting is recommended with at least two plantings, one in early spring and one in late summer/early fall. Corn earworm pressure will be greater in the warmer months, but this can be alleviated by applying spinosad to silks and tassels once they appear.

We recommend planting sweet corn using a walk-behind planter like our Hoss Garden Seeder. Once plants emerge, thin plants to 6-8" depending on adequate irrigation. If drip irrigation is used, in-row spacing may be as close as 6". If water is scarce, wider in-row spacing will be necessary. For pollination purposes, corn should be planted in a square plot with rows on 30-36" spacing. Planting a few long rows will result in poor pollination and the absence of kernels on the cobs.
