Saffron Crocus Bulbs – Crocus Sativus, Grow Your Own Saffron Spice, Fall Planting

Crocus sativus is the source of the world's most expensive spice — and you can grow it yourself. Each autumn-blooming crocus produces stunning purple flowers with three vivid red stigmas (the saffron threads), hand-harvested for one of the most prized culinary ingredients in the world. This is a fall-blooming crocus — distinct from spring-blooming crocus varieties — and it produces flowers from September to October. Whether you want to harvest your own saffron for paella, risotto, or golden saffron milk, or simply enjoy the gorgeous purple autumn blooms, Crocus sativus is a rewarding and unique addition to any garden.

Important: Plant bulbs as soon as they arrive to ensure fall blooming. You'll need at least 20 bulbs for a first-year harvest. Not all bulbs may bloom in the first season — wait until the following autumn for an increased supply. Do not confuse with Colchicum (autumn crocus) — Crocus sativus is the true saffron crocus and is edible.

Harvesting Saffron

Visit flowers on a sunny morning when petals are wide open. Gently pull the three long red stigmas (threads) from each bloom with your fingers. Dry threads indoors on a paper towel and store in an airtight container. Steep in hot broth or milk for 20 minutes to release the golden color. Use in paella, risotto, Indian dishes, or golden mashed potatoes. Mark planting spots — foliage disappears after autumn blooming.

Planting & Care

Choose a well-drained location — if puddles remain 5–6 hours after rain, amend the soil with compost, peat moss, or ground bark to improve drainage. In high-rainfall regions, plant under eaves and water in spring. Saffron Crocus prefer sun or light shade and average moisture in spring.
