Saffron Crocus, scientifically known as Crocus sativus, is a fall-flowering perennial grown for its delicate purple flowers and valuable red saffron stigmas. Each flower produces three distinctive red stigmas that can be collected and dried for culinary use. The plant develops narrow, grass-like leaves and grows from underground corms. Saffron Crocus is suitable for sunny garden beds, raised beds, rock gardens, and containers with excellent drainage. It grows best in well-drained soil with suitable seasonal temperatures and moderate watering.
Produces attractive purple to lavender flowers during the fall flowering season.
Each flower develops three red stigmas that can be harvested and dried to obtain saffron threads.
Develops narrow green leaves that emerge around the flowering period and support the growth of new corms.
Produces daughter corms over time, allowing gardeners to propagate additional plants through division.

The ideal planting time for saffron crocus corms is generally late summer to early fall, particularly August and September in many temperate growing regions. Plant the corms in sunny locations with loose, well-drained soil before the fall flowering season. Planting dates should be adjusted according to local temperatures and climate conditions. In regions with hot summers or different seasonal rainfall patterns, follow locally appropriate planting guidance.
Harvest saffron when the purple flowers open, preferably while they are fresh. Each flower contains three long, bright red stigmas in its center. Carefully remove these stigmas using clean tweezers, avoiding the yellow stamens. Dry the collected stigmas gently and store them in an airtight container in a cool, dark place. Approximately 150 flowers may be needed to produce 1 gram of dried saffron, so a larger planting is needed for a substantial harvest.
Commercial saffron crocus (Crocus sativus) is a sterile triploid plant and does not produce viable seeds for normal propagation. It is propagated through underground corms. Each established mother corm can develop several daughter corms, which can be separated and replanted during dormancy. This makes healthy saffron crocus corms the appropriate planting material for establishing new plants.
