Why Grow This Variety

• A 60–70-day stocked window provides a quicker fresh harvest than bulb onions.
• Mild white shanks and green tops suit raw and cooked dishes.
• Close spacing works in beds and containers.
• The bunching outcome avoids a false storage-bulb promise.

Garden Uses

Use White Lisbon fresh in salads, garnishes, stir-fries, soups, sandwiches, tacos or wraps.

Growing Notes

• Direct-sow shallowly and keep the 2 mm cover continuously moist until established.
• Sow thinly at about 3 × 3 cm or transplant small intact clusters with minimal root disturbance.
• Succession-sow only through suitable cool-to-mild local weather, not by a national year-round calendar.
• Water at soil level and harvest promptly when the shanks reach the desired size.
• Pull and refrigerate for fresh use; do not cure as a storage-onion crop.

Seed safety: “Raw seed” describes the unpelleted sale form, not chemical-treatment status. Do not eat seed or use it for feed or microgreens; follow the physical lot label.
