Cool, crisp hearts with a distinctly clean crunch—Lomar crisphead lettuce forms a tight, well-filled head that feels satisfyingly dense in the hand. The leaves are tender yet sturdy, with a fresh, mild sweetness and a beautifully pale green interior that holds its texture through the season. Grow Lomar for impressive garden-to-table presence, ideal for refreshing salads and elegant, chilled platters where crispness is the star.

Frequently Asked Questions


How often should I water Lactuca sativa during the main growing phase?
During the 6–8 weeks before harvest, keep the soil consistently moist but not waterlogged—aim for light, even moisture with no drying to dust. In full sun, water about 1–2 times per week depending on rainfall, increasing to more frequent watering during warm spells. A good check is to water when the top 1 inch of soil starts to dry, then soak thoroughly so moisture reaches the root zone.
How can I tell when Lactuca sativa is ready to harvest?
Harvest when heads (if growing as a head lettuce type) or outer leaves are full-size and firm, typically around 70 days from sowing for your stated maturity. For leaf lettuce, pick outer leaves once they’re large enough to eat and keep the center growing. Use the finger-firmness test: leaves should feel crisp and not limp, and you should harvest before plants bolt (send up a flower stalk), which makes leaves bitter.
