Lactuca sativa 'Green Ice'
Looseleaf Lettuce
The looseleaf lettuce, ‘Green Ice’, produces crisp, crinkly, bright green leaves in loose heads that are heat tolerant and slow to bolt. This is a great variety to replant for continuous harvest. It is very fast-growing; the leaves are ready to harvest 30 days after planting and heads can be harvested in 45 days.
Lettuce is a cool season, annual vegetable and there are many forms, colors and types. Loosehead or butterhead lettuce is a garden favorite with smooth, thin, buttery leaves and looser heads. When temperatures warm up, the whole leafy clump elongates and grows upwards. At this stage they are no longer good eating. When fully elongated they become topped with tall branched stems covered with pale yellow flowers followed by fluffy white seedheads. Seed savers should collect the mature seeds for another planting.
In temperate zones lettuce is favored as a spring and fall crop and in frost-free, southern zones it is grown as a winter crop. Full sun and light, fertile, nutrient-rich soil and regular water are needed for good production and performance. Plant lettuce seeds in succession for a longer harvest period. Looseleaf types are typically harvested leaf by leaf. Just gather some of the attractive outer leaves and allow the plant to continue to grow until maturity. Once plants begin to bolt, pull them or allow them to set seed for collection.
