Arenaria congesta is a species of flowering plant in the pink family known by the common name ballhead sandwort. It is native to western North America from central Canada to the American southwest.

Description[edit]

This is a perennial herb forming a tuft of slender upright stems up to about 40 centimeters tall. The leaves are needlelike to thready, up to 8 centimeters long and only a few millimeters wide. They may be fleshy or flat and they often have a very sharp tip. Most of the leaves are located in a patch at the base of the plant, and there are a few scattered along the mostly naked stem.

The inflorescence is an open or rounded cyme of five-petalled white flowers. The fruit is a toothed capsule containing several reddish seeds.

Uses[edit]

The plant was used for a variety of medicinal purposes by Native American groups, including the Shoshone.
