Best OP sweet corn?

Hiya folks!

Best sweet corn for zone 4b/5a?

By best... sweet, good yield, open pollinated?

Yep.
That.
Thanks

Have you seen Joseph's Lofthouse Astronomy Sweetcorn?



I wanted to grow some last year but my husband confiscated the packet and grew it in one of his gardens, but where the wild boar could reach it.  And they destroyed the lot.

I kept half the seeds back though and this year I'll be planting it where I can guard it a bit more closely.

Charles,

Don't know how easy it is for you to get seed from outside of Canada, but the following was bred just south of your border in the Red River Valley (south of Winnipeg):  https://www.victoryseeds.com/corn_sunshine.html

That 'Sunshine' variety has worked well for us....can't compete in yield and sugar content to the modern hybrids, but it's reliable and good tasting.  You may wish to look at the other open-pollinated varieties they offer as well.  Good luck!
