Would it be too late to sow "Sepp Holzer" grain? I'm located in Central NY, zone 5. . . More like zone 4 given my elevation and all the damn wind. Last frost date I believe is somewhere around the middle of October, sometime before and sometimes after given the year.
Based on that comment, I would say that now is the time to plant.
It is a perennial rye and typically rye is planted in the fall.
I hope this helps.
