Last year, I grew Mirai350 BC triple-sweet hybrid and the kids loved them. You really cant make a mistake in harvest timing with those. DH and I thought they were a little too sugary and not enough corn depth, and the ears were definitely shorter than the farm stand corn, so they might not compare with Silver Queen however. They do make two ears though.
I do want to try Ambrosia hybrid at some point, but haven't got to it yet because I keep experimenting.
We liked Kandy hybrid Corn.
They sell Ruby Queen hybrid corn now.
I've grown Double Red sweet corn before -- trick is to pick them at the right time if you want to eat them as sweet corn. But if you let them go and turn red and then to mature corn, they make wonderful corn meal, too.
This year, I'll be experimenting with seeds of some corn that I intentionally hand pollinated and crossed -- jumbled up mixture of Mirai 350 bc, Kandy Corn , Double Red, Glass Gem (not sweet corn -- more for popping and flour)..... I'm hoping to eventually get colorful sweet corn.
