The Northern Extra Sweet Hybrid corn is the earliest supersweet variety available, producing large 8 in. cobs that are filled to the tip with sweet kernels. This hybrid showcases enhanced emergence and vigor, making it well-suited for cool, wet soil conditions. Its texture is "crunchier" than many other types, and it boasts a longer shelf life, making it an excellent choice for your garden.

Size: Mature cobs reach 8 in. in length, growing on tall stalks that typically stand around 5 to 6 ft.

Yield: This hybrid corn variety produces high yields, with cobs developing fully even in less-than-ideal conditions.

Taste: Exceptionally sweet kernels with a delightful crunch, offering a burst of flavor that makes this corn perfect for fresh eating.

How to use: Ideal for boiling, grilling, or incorporating into salads for a sweet touch. Enjoy it fresh off the cob or preserved for later use.

Planting tips: Sow when danger of hard frost has passed, in rows 36 in. apart, at a depth of 1.5 in. with 3 seeds per 12 in. of row. Corn prefers a soil temperature of at least 15°C for optimal germination.

Harvest tips: Harvest cobs when they are plump and kernels are firm; look for vibrant green husks and tender, well-filled cobs for the best flavor.

I bought this seed to plant in spring 2026. When I got the package I saw a red warning at the bottom which said "Do not use this seed for food or feed. It has been treated with Thiamethoxam, Dividend Extreme, Polymer and Vibrance Cinco. Use for seeding purposes only." I looked it up and while those products (chemicals) protect the seed from pests and diseases to obtain higher yields, care must be taken to prevent contamination of grain going into the food or feed market. This is due to the potential for treated seed to enter the food or feed chain, which could lead to health risks or contamination of food products. Yikes!

My seed does not even look like corn seed. The polymer coating makes the seed pink.

T&T please have this warning shown on your website so people who purchase seeds know in advance and do not waste their money on chemically altered seed for food.

We have always had good luck with this corn. We have a good garden spot for growing corn. We get 600 to 1000 cobs on a package depending on how many rows we plant, usually 6 to 8. Of course, a lot of cobs are given away. About 98% of the seeds grow. Long and full to the end cobs.

I've been looking for Northern extra sweet hybrid for a few years and found it on your website. Excellent quality seed almost 100% germination and the growth is almost double my other sweet corn varieties. Thank you!

I have grown it for 4 years now. Early maturity is what I need for success. I live in a frost prone area and in 6 years only had corn make it to maturity once. This variety has come thru each time. 2025 it froze real hard in 3rd week of June. Corn was up at least a foot high and looked terrible, I left it and we still ate corn by August with a reasonable yield. I had nearly given up on trying to grow corn. Thanks for making new varieties available.
