Saffron Crocus: Growing Your Own Precious Spice

The Real Source of Saffron

Yes, saffron comes from a crocus—but specifically the fall-blooming Crocus sativus, not the spring-flowering Crocus vernus. The prized spice is the stigma (female part) of the flower, harvested annually.

Planting and Growing Saffron Crocus

Plant corms in early summer for September blooms. They prefer afternoon shade and fast-draining soil; a 1:1 mix of pea gravel and soil conditioner works well. Crucially, ensure you're buying Crocus sativus, not Colchicum autumnale (autumn crocus), which is highly toxic.

Harvesting Your Own Saffron

Each flower produces three red stigmas. Carefully pluck them when the flowers open, dry them, and store in an airtight container. A small planting yields a modest but incredibly fresh supply of the world's most expensive spice.
