Originating in southern China, celtuce is botanically a lettuce. Harvest when the edible stem thickens and reaches a length of 8-10". The tender stems have a flavor that is mild to slightly bitter, and are typically sliced and used in stir fries and soups. Crops grown in cool weather will be milder. The young leaves may also be used in salads. Grow just like head lettuce. In rows 18" apart, transplant seedlings 8-12" apart or sow seeds every 1" and thin to the same spacing. See lettuce "Growing Information" for details. MT0-30. Avg. 24,000 seeds/oz. Packet: 500 seeds.
