Lettuce 'Ice Queen'
Also known as Reine des Glaces, this iceberg lettuce excels in cold tolerance, making it perfect for early or late planting. Its frilled, mild outer leaves can be used as leaf lettuce or baby greens. With a darker green colour and slightly bitter interior, it's widely considered the best iceberg lettuce variety.
The best lettuces are grown fast. Grow them in beds that have just been vacated by peas or beans as all leaf crops, especially lettuce, enjoy plenty of nitrogen. Loose soil with plenty of organic matter will retain moisture and added potash will see them grow without check. Premature bolting and subsequent bitterness is usually the result of stress caused by poor transplanting techniques, damage to their shallow roots, lack of fertilizer or lack of water during hot periods. Mulch well to conserve moisture.
