A mixture of three of the best lettuce for growing in cooler temperatures: 'Arctic King' (butterhead), 'Imperial Winter' (butterhead), 'Winter Density' (semi-cos) famed for their ability to withstand the heat of summer and provide fresh heads of tasty lettuce during the colder months. - Growing instructions: Early in the season sow into trays or modules in the greenhouse or on a windowsill. Thin seedlings to 20cm apart and harden off before planting out, allowing 20cm between plants. Later sowings from autumn onwards do best in a coldframe or in the greenhouse borders but can be sown direct where they are to grow in shallow drills. Protect from slugs and cover early and late sowings with a cloche. Make a late sowing made in October in a coldframe or in a greenhouse border to grow on right through winter.
- Sow: August to October
- Harvest: March to May
