This is an appealing, crisp leaved iceberg lettuce also known as 'Ice Queen' which stays crunchy even on hot days. The medium sized heads are slow to run to seed and have attractively edged leaves.
Sow outdoors thinly, from March to July where they are to crop, 1.5cm deep, directly into finely-prepared, fertile, moisture-retentive 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. Harvest from June to October.
