Helping You Become a More Successful Gardener
LACTUCA sativa 'Green Oakleaf'
Looseleaf Lettuce, Oakleaf Lettuce
Looseleaf lettuce is one of the easiest to grow in home gardens. The very old heirloom, ‘Green Oakleaf’, was introduced in the 1800’s or earlier and is still popular today. Its attractive, lobed green leaves form an open rosette and have a mild, delicious flavor, even when subjected to midsummer heat. It can be harvested continuously through the season if planted in succession. The leaves are ready to harvest in 40 to 50 days and the heads 60 to 65 days after planting.
Looseleaf lettuce is an annual green grown for its open rosettes of crisp flavorful leaves. 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. Once lettuce is subjected to hot weather and begins to bolt its flavor usually becomes bitter. At this stage, pull them or let them set seed for collection.
This is a pretty cultivar for container as well as garden culture.
