Unusually beautiful iceberg lettuce from Italy that grows well even in Scandinavia. The shiny, bright green outer leaves are deeply serrated, and encloses a large, crunchy and sweet head. Regina dei Ghiacci - "Ice Queen" - are harvest-ready for a long time and can withstand wet weather better than most iceberg lettuces. A portion contains about 150 seeds.

SowingSow thinly about 0.5 cm deep! The seeds germinate weill in light and a temperature around 18°C to germinate. A higher temperature causes late and bad germination. Lettuce can be forced very early in a green-house (soil temperature at least 5°C) or sown indoors and in hotbeds 3-5 weeks before handle several degrees of frost. Direct sowing can take place as soon as the soil is ready. Water the row before sowing if the soil is dry. That lowers the temperature some when sowing in high summer. To get a supply of lettuce all through summer and autumn, sow successively or several kinds of different growth times!
SpacingThin out early! Iceberg lettuce need a mutual space of 20-30 cm to be able to form heads, 35-50 cm between the rows.
HarvestHarvested when the plant has formed a head.
