You will find lots of people who can give info on gardening in Minnesota.
I have not grown cowpeas but likely there are several cultivars and there may be one that can be grown in the north.
Maybe place your post on cowpeas over in the vege forum and the experienced vege gardeners may know which cowpea is best in the north.
Thanks Caroline. I know there are a few cultivars that will grow up here (at least in a normal year), I just haven't figured out where to buy seeds for them. Also I'd like to hear from any northerners that even know what purple hull peas are ;) and maybe have stories about trying to grow them.
BTW, if you haven't bought your lights yet, I highly recommend these: [edit: forum won't let me post a link, but goto Amazon and search for B00HEYCRI8 it should bring up a 4 foot 4-lamp T5 fixture] The price jumps around all over the place; I was going to buy another fixture last year and they were over $100 so I bought something else and didn't like it nearly as much. $80 is a fair price.
