Common Cilantro Varieties

Popular cultivars to look for at your local nursery or seed supplier.

Santo

open-pollinated

Slow-bolting variety that stays leafy longer in warm weather than standard cilantro.

Calypso

open-pollinated

Highly bolt-resistant and high-yielding; ideal for warm climates with long growing seasons.

Leisure

open-pollinated

Large-leaved variety that bolts slowly and regrows well after cutting.

Vietnamese Coriander

species

Heat-loving substitute for true cilantro; peppery flavor, perennial in warm zones.

Common Cilantro Problems

What to watch for — and how to fix it before it spreads.

🐛

Pests

Aphids

Light green aphids cluster on stems and umbels, distorting flowers and reducing seed set.

Fix:

Spray with water or neem oil; tolerate light infestations as cilantro is short-lived anyway.

Caterpillars (Parsley Worm)

Striking green-and-black caterpillar that can strip a cilantro plant quickly.

Fix:

Relocate caterpillars to wild carrot (Queen Anne's Lace) — they become Black Swallowtail butterflies.

🍂

Diseases

Damping Off

Seedlings collapse at the soil line shortly after germination, caused by fungal pathogens in wet soil.

Fix:

Use sterile seed-starting mix; water from below; ensure excellent drainage.

Powdery Mildew

White coating on leaves; common in warm, dry weather with cool nights.

Fix:

Improve airflow; direct-sow in well-spaced rows; apply potassium bicarbonate spray.

💡

Common Mistakes

Sowing a single large batch

Cilantro bolts quickly in warm weather, leaving you with none after 4–6 weeks.

Fix:

Sow small amounts every 2–3 weeks from early spring through fall for a continuous harvest.

Growing in summer heat

Cilantro bolts immediately in temps above 80°F.

Fix:

Grow in spring and fall; in hot climates, grow in part shade or choose "slow bolt" varieties like Calypso.

🌾 Seed Saving Guide

🟢 Easy
✅ Open-pollinated — seeds grow true to parent

When to Harvest Seed

Let plants bolt fully. Harvest seed heads when they turn brown but before they shatter.

Processing

Cut seed heads into a bag and shake. Dry for 1 week before storing.

Seed Viability

Up to 3 years when stored cool, dark, and dry.

Pro Tip

Cilantro seed (coriander) is also a culinary spice — you can save the same seeds you'd cook with.
