Red Romaine Lettuce Seeds (Romaine or Cos Type) 1765. Attractive appearance, crunchy texture and a nice buttery flavour. Attractive green leaves are overlaid with deep burgundy colouring. Sweet, crisp heads are 30 cm (12″) tall and rather loosely wrapped. A colourful addition to salads or mesclun mixes. How to Grow 880 seed/gram. Lettuce is a sun-loving cool weather crop that grows best in organic, well drained soil. Sow as soon as the soil can be worked in the spring, then every two weeks thereafter to ensure a continuous supply. Sow about 3 mm (1/8″) deep in rows 45 cm (18″) apart. Gradually thin seedlings to 15 cm (6″) apart. An even supply of moisture during the entire growth period is imperative for success. Harvest by cutting the head off at the base just below the lower leaves. Once lettuce bolts (starts to produce a rapidly growing flower stem) leaves become bitter.
