you can check with your state ag dept at the city hall... for a good list..... I live near Green Bay so I know what you are talking about...... but pretty much most veggies are grown here, cabbage, raddish, beets, Beans,corn, peas, carrots, .... pretty much all of them..... also if you have a hot house or green house you can start them early and plant them after memorial day like watermelon ... califlower, brocclii....ECT...
