We bought through cooperseeds.com and this is my first year for it. It is supposed to be full sunlight plant but I just don't have the experience to say. Friends around Solon have planted the last few years & both turkeys & deer use it when they weren't flooded out. I have it planted along the corn plot & on the side of the rye. I expect that all food sources will be used through winter- I have been told to run a disk over a strip in the fall and uncover some of the tubers to "prime" the turkeys to look for it. This stand was planted in southern Van Buren county. I also have beans, rye, & corn plots.
