A versatile, fast-growing herb that produces fragrant, dark green leaves commonly used in Latin American, Indian, and Asian dishes. While the fresh leaves (cilantro) are prized for their bright, citrusy flavour, the mature seeds (coriander) develop a warm, nutty aroma and can be dried for spice blends or saved for future planting.

This cool-season herb thrives in spring and autumn, as it bolts quickly in hot weather. Regular harvesting prolongs leaf production, but allowing some plants to flower and set seed ensures a continuous supply of coriander for cooking or future planting.

Where Can You Grow Cilantro?

Cilantro thrives in Zones 3-9, preferring full sun to partial shade and well-drained soil. It grows well in garden beds, raised beds, and containers, making it an excellent herb for home gardens and patios.

History and Historical Uses

Cilantro has been cultivated for thousands of years and is one of the oldest known culinary herbs. Native to regions of Southern Europe, North Africa, and Asia, it has long been valued for its culinary, medicinal, and aromatic properties. Cilantro remains a key ingredient in salsas, curries, chutneys, and spice blends across the world.

Canadian Zone Information

Zones 8-9: Direct sow in autumn or early spring for extended harvests.
Zones 5-7: Sow seeds in early spring and again in late summer for best results.
Zones 3-4: Direct sow after the last frost and provide light shade in summer.

How to Grow and Harvest Cilantro

1. Planting: Sow seeds 1cm (1/2in) deep, spacing plants 10-15cm (4-6in) apart.
2. Watering: Keep soil consistently moist but avoid waterlogging.
3. Harvesting:
   • Pick young leaves regularly for best flavour.
   • Allow plants to bolt for seed production (coriander).
4. Bolting Control: Grow in cooler weather or partial shade in summer to slow bolting.

Seed Saving Tips for Future Supply

1. Allow Plants to Flower: Cilantro will produce tall flower stalks with delicate white blooms before setting seeds.
2. Harvest Seeds: Once the seed heads turn brown and dry, cut them and allow further drying in a well-ventilated area.
3. Thresh and Clean: Gently rub seed heads to release coriander seeds, removing any debris.
4. Store: Store dried seeds in an airtight container in a cool, dark place. Properly stored seeds remain viable for up to 5 years.
