Intro: The lettuce you find in your salad bowl are varieties of Lactuca sativa. Common lettuce varieties that you can grow in plant containers in your kitchen garden are black-seeded Simpson, red sails, salad bowl, Tom Thumb, green ice and little gem.
Scientific Name: Lactuca sativa
Plant Type: Leaf vegetable
Light: Full sun (6 or more hours of sun).
Propagation: Buy young lettuce at your local garden shop or grow from seeds. Hot weather will make lettuce plants produce seeds (also called “bolting”).
Misc. Info: Keep your lettuce plants partly shaded if temperatures are high. This vegetable plant is best grown in the spring or fall, as they don’t fare well in temperatures above 80 degrees. Harvest the outside lettuce leaves from your balcony garden as you use them, or harvest the whole lettuce head at once. Pick your lettuce right before you eat it for freshness and best taste, and make sure to harvest your lettuce before it begins producing seeds.
