Lettuce 'Calmar'

Lactuca sativa capitata

Very good taste and heat resistance. Produces large, firm heads with crisp leaves, also excellent for continual harvest of outer leaves when grown vertically. Long harvest period. Thrives in a humus-rich, moisture-retaining and well-drained soil. Water regularly. Good source of vitamin A.

Repeat sowing throughout the season for fresh lettuce all summer.

Trivia: Calmar variety is of "Great Lakes" parentage and adapted to coastal California early spring harvest. The name 'Calmar' combines "cal" from California with the Spanish word for sea "mar".

Pre-cultivation: For earlier harvest, 3-4 weeks before planting out.

Direct sowing: Early, as soon as the soil can be cultivated - July. Water before sowing and keep the seed moist during germination. Lettuce seeds germinate poorly in high heat, not above +20°C.
