Rouge de Hiver means "Red of Winter" referring to the cold weather performance of this tender leaf lettuce.
Lettuce grows well in cool weather, so the first crop can be direct sown when the soil temperature reaches at least 35 degrees F, or as soon as the soil can be worked. If the soil temperature rises above 75 degrees F, the seeds become dormant. Direct sow the seed in rich soil and full sun, spreading them as thinly as possible in rows 1-2' apart; when the seedlings begin to grow, thin them to a distance of 10-12". Succession crops can be grown for fresh lettuce all season in areas with cool summers or warm winters; this is accomplished by planting a new crop every 2 weeks. For companion planting benefits, grow lettuce with onions, cucumbers, or carrots. Also known as Rouge d'Hiver or Red Winter. Annual. 55-65 days. 9-12" height. 10-12" spacing. Produces loose conical heads of bronze/dark red leaves and green centers.
