Saffron Crocus (Crocus sativus) Bulbs – Grow the World's Most Expensive Spice, Lilac Fall Blooms, Easy to Grow, Multiplies Yearly

Minimum: 5+ Bulbs

Grow the World's Most Expensive Spice at Home

Saffron sells for more per ounce than gold, and the reason is simple: each thread comes from hand-harvesting the three tiny stigmas inside a single crocus flower. Saffron Crocus makes that math friendlier in a home garden, sending up lilac blooms each fall that you can harvest yourself, thread by thread, for a genuine homegrown supply of the world's most valuable spice. It's easier to grow than its reputation suggests, and established plantings multiply on their own year after year.

What This Fall-Blooming Spice Crop Actually Is
Crocus sativus, commonly called saffron crocus, is a fall-blooming perennial grown from corms, the true source of culinary saffron, harvested from the three red-orange stigmas found inside each lilac-purple flower. Plants send up grass-like foliage and flowers in fall, considerably later than most spring-blooming crocus species, with each corm typically producing one to a few flowers per season. The stigmas are hand-picked from each bloom and dried to become the saffron threads used in cooking, a labor-intensive process that explains the spice's high market value, though a home planting easily supplies enough for personal use. Corms multiply underground over time, naturally increasing a planting's flower and saffron yield in subsequent years without replanting. Hardy in USDA zones 6 through 9.

In the Garden & Kitchen

• Homegrown saffron harvest: Hand-pick the red-orange stigmas from each fall bloom and dry for culinary saffron.
• Fall-blooming bulb display: Enjoy the lilac flowers as a genuine late-season bloom when little else flowers.
• Naturalizing planting: Let corms multiply undisturbed for an increasing harvest in future years.
• Culinary use: Use homegrown saffron threads in rice dishes, stews, baking, and other classic saffron recipes.
• Gift-worthy harvest: Dry and package homegrown saffron as a genuinely valuable homemade gift.
• Naturalized meadow or border planting: Tuck corms into a border or lawn area for fall color and harvest.

Planting Saffron Crocus Corms

• Start method: Plant corms directly in the ground; no indoor starting required.
• Timing: Plant corms in late summer to early fall, 6 to 8 weeks before the first expected frost.
• Planting depth: Plant corms 3 to 4 inches deep, pointed end up.
• Spacing: Space corms 4 to 6 inches apart to allow room for natural multiplication over time.
• Sunlight: Full sun.
• Soil: Well-drained soil is essential; corms are prone to rot in wet or heavy ground.
• Watering: Moderate water at planting; established corms tolerate dry summer dormancy well.
• Bloom time: Flowers appear in fall, roughly 6 to 8 weeks after planting in the first year.
• Harvest: Pick stigmas by hand from each flower as soon as it opens, then dry for storage.
• Multiplication: Corms multiply underground each year, increasing bloom and harvest without replanting.
• Hardiness: Reliable to zone 6; a genuinely perennial bulb where winters allow it to persist.
