any of certain small, fleshy annual plants of the genus Portulaca (40-100 species), of the family Portulacaceae. The plants have prostrate, often reddish stems, with spoon-shaped leaves and flowers that open in the sunlight. The common purslane (P. oleracea), or pusley, is a widespread weed, recognizable by its small yellow flowers. P. oleracea sativa, known as kitchen garden pusley, is grown to some extent as a potherb, mostly in Europe. Rose moss (P. grandiflora), a trailing fleshy species, is cultivated as a garden ornamental for its brightly coloured, sometimes doubled flowers. All plants of the genus are known for their persistence; they grow well even in dry waste soil and can retain enough moisture to bloom and ripen seeds long after they have been uprooted. The capsules, which open by a lid, scatter many small seeds of great longevity.
