Any way you look at it, it is still ryegrass and is still primarily cow food. Plant it next to a field of alfalfa, soys, or clover and you'll most likely have nothing but grasshoppers feeding in that grass. Besides any of that, I have seen many pieces of literature that say it may not survive winter in Zones 4 or below. I hope all your inquiries are from guys south of MN. Many of the US users are from places like WA or OR, where the climate is nowhere near as severe as we see in the upper midwest and it looks like they ship this seed "down under" as well, the Aussie's and Zealanders like it. The only thing I have seen on northern survival that looks promising is that the variety AberDart seems to be doing well in the UP of MI. I remember Lickcreek was pretty impressed with the stuff he planted down in IA, but I am skeptical on how well it would do much farther north than that, especially if we got extreme cold with little to no snow cover.
