Same here! The description sounds almost too good to be true. They're $30 for 25 of them through NY state. I think for that price I'll try to get some next year if I don't find any other reasonable sources.
The zone description varies from 3 to 6 depending on where you look so it's possible there are more cold hardy versions out there. I'm in zone 5 too.
