My area has a short growing season so I look for early varieties. Incredible corn certainly lives up to it's name. My first planting goes into the ground at about the end of May, 2nd about 2 weeks later, and 2 weeks after that the 3rd planting. This gives us corn until frost. This variety replaced Early Sunglow which I grew for many years. The ears are larger, and it is sweeter but still has great corn flavor. It keeps quite well on the stalks and takes longer than the Early Sunglow to get starchy. It's my new favorite!

The best sweet corn I've ever eaten. I agree, it keeps very well in freezer. Taste is exceptional even after a year in the chest freezer. Big ears, beautiful yellow.

This cultivar is my favorite sweet corn, not only for it's great pollination (skips in the cobs are very rare), but also for it's keeping ability. We found some 2 year old frozen corn in the bottom of the deep freeze.....still exceptional.
