Claytonia perfoliata, also known as miner's lettuce, Indian lettuce, spring beauty, or winter purslane, is a flowering plant in the Montiaceae family.
Claytonia perfoliata is a tender rosette-forming plant that grows to a maximum of 40 centimetres (16 in) in height, but mature plants can be as short as 1 centimetre (0.39 in). The cotyledons are usually bright green (rarely purplish- or brownish-green), succulent, long and narrow. The small pink or white flowers appear from February to May or June and are grouped 5–40 together. Mature plants form a rosette; they have numerous erect to spreading stems that branch from the base. C. perfoliata is common in the springtime, and prefers a cool, damp environment. The plant first appears in sunlit areas after the first heavy rains of the year, though the best stands are found in shaded areas, especially in the uplands, into early summer. As the days get hotter and drier, the leaves turn a deep red color as they dry out. Invasive in North America.
