Florida Lettuce is a herbaceous plant that can be classified as either annual or biennial, originating from the eastern and central regions of the United States, and it is prevalent throughout North Carolina. In its natural habitat, this plant is capable of self-seeding. It can grow up to 6 feet in height and produces an inflorescence featuring numerous flower heads, each with 10 to 20 blue or white ray florets, though it lacks disc florets. While the leaves are edible, they have a bitter flavor and are similar in appearance to dandelion leaves. For the best taste, it is recommended to consume the younger leaves raw in salads, while the older leaves are better suited for cooking.

This plant thrives in moist, fertile soil and prefers conditions ranging from shade to partial shade.
