Rooreh (Claytonia perfoliata) is a trailing annual herb in the Montia family, native to a large portion of western North America, including almost every county in California. The plant has small white flowers with five petals that bloom from February to May or June. The leaves are round, succulent, and edible, commonly known as miner's lettuce, along with its subspecies Claytonia perfoliata ssp. perfoliata.
