Lettuce comes in all shapes and colors, sometimes with green, golden, purple, bluish, reddish and multicolored leaves. Lettuce is in the aster family, along with dandelions and sunflowers: one of the biggest plant families on the planet! Lettuce’s scientific name, lactuca sativa, comes from the way that the stem oozes a white liquid like milk when it breaks.
Ancient Egyptians were cultivating lettuce 6,000 years ago. 23 million metric tons of lettuce are eaten each year by people all over the world!
