Portulaca pilosa is a beautiful flowering succulent native to the Americas, from the southern United States to Brazil (though it is found worldwide, and some scientists believe it may be native to Asia). It can grow in various environments and is currently being studied for its medicinal value.

It is an annual, roots fibrous to slightly fleshy. Leaf blades are linear to oblong-lanceolate, terete to hemispheric, petals dark pink to purple, and seeds black to leaden; surface cells are loosely arranged short-tuberculate. Its habitat is dry soils, beaches, disturbed habitats, roadsides, and railroads on limestone, granitic, and sandstone outcrops.
