First cultivated in the Mediterranean region, saffron is, by weight, the most expensive spice in the world. It comes from the saffron crocus, Crocus sativus. Considering the high price this spice fetches at market, you might be surprised to discover how easy it is to grow.

How to grow saffron crocus

  • The fall-blooming, purple-flowered saffron crocus grows from a bulb-like structure called a corm. The corms are planted in the spring or early fall.
  • Saffron crocus smells a little like vanilla and spice, and the dried stigmas add a distinct flavor to foods like Spanish paella, rice dishes, and bouillabaisse.
  • To plant saffron crocus, start with high-quality corms. They can be purchased for a reasonable price from several different online companies, including Nature Hills Nursery and Brent and Becky’s Bulbs.
  • Chose a planting site that is very well-drained and has soil rich in organic matter.
  • Plant the corms in spring or in the early fall, to a depth of about four to six inches.
  • Once planted, you won’t see anything sprout from the bulbs until late fall.
  • When the flower comes into bloom in the autumn, the elongated, orangeish-red stigmas are plucked from the flower. The flowers are small, and the stigmas are like little orange threads, making harvesting large quantities of this spice quite time-consuming (hence, its hefty price).
  • Spread the harvested stigmas on a cookie sheet to dry in a warm room until they easily crumble.
  • Each bulb produces one flower and each flower produces three stigmas.
  • As soon as the flowers fade, you can gently dig up the crocuses and separate the bulbs, replanting them immediately. Doing this yearly quickly results in a large colony, but if you only want to take on this task every three or four years, that’s okay. Just remember to divide them before the corms become over-crowded and production is affected.
  • Saffron crocuses are hardy down to -10 degrees F. If you live in a region where temperatures regularly dip below that limit, be sure to mulch the planting site with several inches of straw or compost soon after the plants are finished blooming.
  • When stored in an air-tight container, dried saffron remains fresh for up to two years.
