The new USDA hardiness map puts me solidly in zone 6A. I wonder how accurate this really is? I guess I trust it more than the arbor day foundation’s map (which puts Minneapolis as zone 5 but as many people living there can attest, most plants rated zone 5 do NOT survive the winter there, while USDA still has it as zone 4b which makes sense since it gets below -15 at least two or three times a winter making it NOT zone 5 which only gets to -10). I know there is a lot to hardiness other than minimum temp BUT minimum temp DOES still have an effect so I’m just going to continue ignoring the arbor day foundation. I also think this means I need to experiment more with my Chicagoland garden because really what’s the point of living in this craphole if I’m not going to at least have fun with the plants?
