Market garden quality. Larissa thrives in cool conditions in early spring or in the autumn. Ventilate when kept in a greenhouse in warm weather. Also fine for cultivation outdoors with summery weather. As of mid March can also be sown outside in the garden. Keep seeds cool in the summer. Thin out liberally and keep sufficiently moist during warm weather. Runs to seed slowly and does not easily get marginal blight. Lettuce can already be sown at low temperatures (> 10ºC).
