Romaine lettuce facts for kids
Romaine or cos lettuce (Lactuca sativa L. var. longifolia) is a popular type of lettuce known for its long, sturdy leaves and crisp texture. It's a leafy green vegetable that adds a fresh crunch to many meals. Its flavor is a bit stronger and slightly more bitter than some other lettuce types, but it's still very refreshing. Romaine lettuce is special because it's one of the few kinds of lettuce that can be safely fed to iguanas as part of their diet.

What is Romaine Lettuce?
Romaine lettuce is a member of the daisy family, just like sunflowers! It grows in a tall, upright head with long, dark green leaves that have a strong rib down the center. These ribs are very crunchy, especially towards the bottom of the leaf. The name "cos lettuce" comes from the Greek island of Kos, where it was once very common.
How Romaine Lettuce Grows
Romaine lettuce is an annual plant, which means it completes its entire life cycle in one growing season. It starts from a tiny seed, grows into a full plant, produces its own seeds, and then dies. Farmers usually plant romaine lettuce in cool weather, either in spring or fall, because it doesn't like too much heat. It needs plenty of sunshine and water to grow big and healthy.
From Seed to Salad Bowl
When you plant a romaine seed, it first sprouts small leaves. As it grows, the leaves get longer and form a tight, upright head. Farmers harvest romaine lettuce by cutting the whole head from the ground. Sometimes, they might also pick just the outer leaves, allowing the inner leaves to continue growing. This way, they can get more harvests from one plant!
