I've tried a few heirloom sweet corns. The only variety I can remember by name that I rejected (for flavor) was Country Gentleman. (It seemed pretty much like the pure "glue" taste to me at the time.) The two I might grow again are Golden Bantam and Ashworth. Ashworth made a wimpy plant, but it might have had slightly sweeter corn than Golden Bantam and it was extra early. I've gotten to where I prefer hominy from the local heirloom dent corn I grow, and I don't care as much for sweet corn any more, but after all these years I really ought to try some of the field corn I grow in the milk stage.

What varieties do you have FF?

"Because of that crappy thing - cross pollination - the minority has to eat what the majority likes!" Not so much due to cross-pollination, as to changing tastes, and the diminishing number of varieties grown commercially. Nearly all of the ubiquitous bi-color sweet corn sold commercially is now GM... a choice made by farmers, not consumers. Basically, the only choice left to the consumer is to take it or leave it (I choose the latter). As with several other vegetables, the evolution of sweet corn has tended to focus on the "sweet" aspect. That is not all bad, since - intentionally or not - the evolution of tenderness has gone hand in hand with that. I've grown & enjoyed several of the older Su sweet corns, but have to admit that I prefer some of the Se hybrids now. IMO they tend to be the best compromise between the older corn flavor, and the super sweets. The fact that many of those have better disease resistance, and better husk cover, is an added bonus. The vendor I've used for years dropped my favorite variety last year (Miracle), I hope I can find an alternate source, and that it has not been discontinued.

You might try Southern Exposure Seed Exchange. They do have those varieties available, as well as other interesting ones, but maybe not in those quantities. What I'm having to do is increase my own seed stock year by year. Good luck to you!
