i bought clary sage for my local feed store and the packet said that it was a biennial, which is fine but when i looked it up, all i could fine was it wasn't hardy in zone 5 but i could find nothing else on being hardy in zone 4. So my question is: can it overwinter in my zone 4. if not, can i grow it in a pot this growing season, than overwinter in the house and plant it out the next year?

thanks East
