Common Basil Varieties

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

The classic Italian basil with large, fragrant leaves — the standard for pesto.

Thai Sweet Basil

open-pollinated

Anise-scented variety with narrow leaves; essential in Southeast Asian cooking.

Lemon Basil

open-pollinated

Citrusy, light-scented basil; excellent in salads, fish dishes, and teas.

Purple Ruffles

open-pollinated

Striking deep purple variety used as a garnish and in flavored vinegars.

Common Basil Problems

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

🐛

Pests

Aphids

Soft green or black insects on new growth; excrete sticky honeydew that attracts ants.

Fix:

Blast with water; plant near marigolds; apply neem oil or insecticidal soap.

Japanese Beetle

Metallic green beetles skeletonize leaves in midsummer.

Fix:

Handpick in the early morning; knock into soapy water; use row covers during peak season.

Slugs

Ragged holes in leaves overnight; shiny slime trails visible in the morning.

Fix:

Apply diatomaceous earth around plants; use beer traps; avoid watering in the evening.

🍂

Diseases

Basil Downy Mildew

Yellowing between veins on upper leaf surface with gray fuzzy spores beneath; spreads rapidly in humidity.

Fix:

Plant resistant varieties (e.g. Amazel, Rutgers Devotion); improve airflow; avoid wetting foliage.

Fusarium Wilt

Seed-borne fungal disease causing sudden wilting, streaky brown stems, and plant death.

Fix:

Buy certified disease-free seed; rotate planting location annually; destroy infected plants.

💡

Common Mistakes

Letting it flower (bolt)

Once basil flowers, leaves turn bitter and production drops rapidly.

Fix:

Pinch flower buds weekly; make a final large harvest and preserve as pesto when bolting begins.

Watering overhead

Wet foliage is the primary trigger for downy mildew.

Fix:

Water at the base; water in the morning so leaves dry quickly; use drip irrigation.

Planting out too early

Basil dies in a frost and sulks when temps are below 50°F.

Fix:

Wait until nights are reliably above 55°F before transplanting outdoors.

🌾 Seed Saving Guide

🟢 Easy

✅ Open-pollinated — seeds grow true to parent

When to Harvest Seed

Let a few stems bolt and flower fully. Harvest seed heads when brown and completely dry.

Processing

Shake dried seed heads into a bag, separate seeds from chaff by blowing gently.

Seed Viability

Up to 5 years when stored cool, dark, and dry.

Pro Tip

Basil cross-pollinates between varieties — isolate by 150 feet or bag flower heads to keep varieties pure.
