The Story

Plant Bio

Crocus sativus, saffron crocus, is an autumn-flowering corm six to ten inches high. Five to eleven narrow upright leaves emerge before or with the flowers, and lilac-purple saucer-shaped blooms open in autumn, each carrying three long branched red stigmas — the saffron itself — above golden anthers.

It is a sterile cultivated plant that sets no seed and exists only because people have propagated its corms for millennia. The crop is the three red stigmas from each flower, picked by hand on the morning they open, which is why saffron is the most expensive spice by weight: roughly 150 flowers make a single gram dried.

Uses & Benefits:

Ornamental UsesLilac-purple autumn flowers with vivid red stigmas, at a season when few bulbs are out.
Practical UsesThe source of saffron, the most valuable spice by weight, harvested by hand from each flower.
Ecological BenefitsSterile and seed-free, so it spreads only by corm division and never escapes.

Planting

How to Grow

  1. Plant corms in late summer, four inches deep.
  2. Choose full sun and sharply drained soil.
  3. Expect flowers in autumn, weeks after planting.
  4. Pick the red stigmas on the morning flowers open.
  5. Dry the stigmas immediately and store airtight.
  6. Lift and divide congested corms every few years.

Pro Tip

Pick the stigmas the morning each flower opens — leave it a day and the quality drops sharply.
