Mr Fothergill's Lettuce Romaine Ballon Seeds, Renowned, large sweet 'cos'. For the crispest, freshest heads, pick in the cool of early morning or late evening. Romaine lettuce is the best type for braising as well as for use in salads.

Sow outdoors thinly where they are to crop, 1.5cm deep, directly into finely prepared soil which has already been watered. Allow 30cm between rows. Early sowings may benefit from cloche protection. Seedlings usually appear in 7-14 days. Thin out to 20cm apart. Water well until plants are established. Regular sowings made every two to three weeks will ensure a continuous supply.

• Large solid heads, with a crisp, crunchy texture
• Excellent flavour. Grows well even in adverse weather
• Good source of vitamin C and vitamin A
