I try not to buy dried herbs if I can help it, I grow as many as possible myself. But there is one thing I cannot manage to grow and that is coriander, no matter how I try, they always die. The big bummer is, I cant buy it in Spain either, they just dont use it here, or if they do, they dont sell it anywhere that I know of.
So, the last herb I would have bought would have been coriander, if indeed there was any to buy.
