Sallat, Huvud-, Merveille des

Well-known 19th century variety of red-tinted head lettuce with dent leaves. The heads become relatively loose. Decorative in salads. Repeated sowing gives access to fresh lettuce heads all summer. Thinning harvest before the plants start to crowd and then harvest whole plants as you go. Thrives in a loamy, moisture-retaining and well-drained soil. Water regularly.
