OP. The next best thing! Check out this YouTube video on celtuce. Also known as Chinese stem lettuce. Harvest when the stem thickens and reaches a length of 8-10″. The peeled tender inner stem has a flavor that is mild to slightly bitter, and is 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. 55 days.
