Cardionema ramosissimum is a beach-dwelling plant of the pink family, Caryophyllaceae, which is known by the common name sandcarpet. This is a flat or clumping mat-forming perennial plant which grows along the coastline of western North America, as well as Chile. >From a taproot it extends many petite to sprawling stems up to 30 centimeters long and covered in very tiny leaves, which are about a centimeter long and needlelike. Filling in the spaces between the spine-shaped leaves are long stipules. The plant bears tiny woolly flowers. This thick plant forms a blanket on the sand and can be used for erosion control on beaches.
