Native to the mountainous regions of southwestern Europe from the Pyrenees to Portugal, this evergreen herbaceous perennial is a member of the carnation family, Caryophyllaceae, that also includes, pinks, baby’s breath, and Irish moss. It grows 2-9″ tall from a shallow root system and forms a softly hairy, dense mound of lanceolate to ovate, green to gray-green leaves that are 1/8 to 1″ long. From late spring to early summer, dense cymes of 2-10 white, flat, 1/2-1″ wide flowers appear on 1″ stalks. The plants spread slowly and are a good choice for a groundcover, edging in a border or along paths, or for rock , wall, or trough gardens. The genus name, Arenaria, comes from the Latin word arena, meaning sand, and refers to the soil of the natural habitat of most of the plants in the genus. The specific epithet, montana, is from the Latin word mons, meaning mountain and refers to the native habitat of the plant.
