Common Cilantro Varieties
Popular cultivars to look for at your local nursery or seed supplier.
Santo
Slow-bolting variety that stays leafy longer in warm weather than standard cilantro.
Calypso
Highly bolt-resistant and high-yielding; ideal for warm climates with long growing seasons.
Leisure
Large-leaved variety that bolts slowly and regrows well after cutting.
Vietnamese Coriander
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
Light green aphids cluster on stems and umbels, distorting flowers and reducing seed set.
Spray with water or neem oil; tolerate light infestations as cilantro is short-lived anyway.
Striking green-and-black caterpillar that can strip a cilantro plant quickly.
Relocate caterpillars to wild carrot (Queen Anne's Lace) — they become Black Swallowtail butterflies.
Diseases
Seedlings collapse at the soil line shortly after germination, caused by fungal pathogens in wet soil.
Use sterile seed-starting mix; water from below; ensure excellent drainage.
White coating on leaves; common in warm, dry weather with cool nights.
Improve airflow; direct-sow in well-spaced rows; apply potassium bicarbonate spray.
Common Mistakes
Cilantro bolts quickly in warm weather, leaving you with none after 4–6 weeks.
Sow small amounts every 2–3 weeks from early spring through fall for a continuous harvest.
Cilantro bolts immediately in temps above 80°F.
Grow in spring and fall; in hot climates, grow in part shade or choose "slow bolt" varieties like Calypso.
🌾 Seed Saving Guide
🟢 EasyWhen 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.

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