Saffron is expensive. Very expensive. But you can actually buy and grow your saffron crocus, Crocus sativus (in zones 6-9). With corms (bulbs) going for about 50 cents each and 3 stigmas per flower, let’s see…500 stigmas in a gram… a gram at Penzey’s for $6.49… well, I guess it’s still cheaper to buy it at the store instead of starting your own little saffron farm.
