Batavia Lettuce Seeds (Lactuca sativa)

Lactuca sativa var. capitata

Batavia lettuce, blonde Batavia, crisphead lettuce: halfway between butterhead lettuce and loose-leaf lettuce, it forms a loose head with wavy, blistered leaves. Its greatest asset can be summed up in one word: crunch. Where butterhead lettuces are soft and melting, Batavia lettuce holds its texture when bitten into and stands up better to dressing.

Characteristics:

• Crunchy foliage: thick, wavy and blistered leaves with a characteristically firm texture.
• Old variety: a reliable choice for the vegetable garden, valued for its tenderness and good texture.
• Holds its shape on the plate: it does not immediately wilt once dressed.
• Flexible cultivation: outdoors, under a cold frame or in a polytunnel, depending on the season.

Sowing advice:

• Exposure: full sun for the first spring sowings, partial shade in summer: like all lettuces, heat and long days trigger bolting.
• Soil: rich in humus, cool and well drained. If your soil is heavy, lighten it with sand and compost. The soil must remain consistently moist: drying out causes lettuce to bolt and become bitter.
• Method: sow barely covered, as the seeds need light to germinate. From March to May, sow directly in the ground every two weeks to stagger the harvest. Warning: above 25 °C, lettuce seeds enter dormancy and will no longer germinate — sow in the shade or at the end of the day in very hot weather. See how to sow your seeds.

Planting advice:

• Transplant at the 4- or 5-leaf stage, spacing plants 30 cm apart, without burying the crown: this is the main cause of rot in young lettuces.

Care advice:

• Water regularly at the base, in the morning, without wetting the foliage. Mulch to retain moisture.
• Lightly hoe between the rows to aerate the soil.

Harvesting advice:

• Cut the head at ground level as soon as it is well formed. Do not wait: as soon as the centre begins to rise, bolting has begun and bitterness sets in.
• Leave the stump in the ground: it often produces a few tender shoots to harvest.

Beneficial associations:

• Its rapid growth makes it an excellent intercrop between slower-growing vegetables. It grows well with carrots, radishes, strawberries and leeks. Also see Merveille des Quatre Saisons lettuce and vegetable garden companion planting.

Benefits for biodiversity:

• Let one plant bolt at the end of the season: its small yellow flowers attract hoverflies and solitary bees, while its seeds feed goldfinches.
• Its rapid growth helps keep the soil covered between two main crops.

Uses:

• Raw in salads, where its crunch makes all the difference, or in burgers and sandwiches — it holds up much better than butterhead lettuce. The outer leaves can be braised or used in a velouté.

Harvesting your own seeds:
Let a healthy plant bolt: it produces a tall flower stalk followed by tufted achenes, which should be harvested as they reach maturity in stages. As lettuce is self-pollinating, cross-pollination is rare — making it an ideal species for beginners in seed production. See how to save your seeds.
