Alternanthera caracasana (commonly known as Caracas bleeding herb, wild
purslane or chicken herb) is a herbaceous, perennial plant belonging to
the Amaranthaceae family. Although native to the tropical and
subtropical regions of Central and South America, it has now become
naturalised in many parts of the world as a ruderal species and, on
occasion, as a persistent weed.
It develops pubescent (hairy) stems
that grow completely close to the ground. This enables it to form dense
ground cover and go easily unnoticed.
Due to its low-growing habit
and strongly rooted stems, it withstands constant foot and animal
traffic without suffering severe damage.
Its leaves are opposite,
oval or rounded. Its inflorescences are small axillary glomerules (white
or whitish) bearing spiny tepals, which act as ‘harpoons’ to attach to
surfaces and spread the plant.
This plant thrives mainly in highly
nitrified environments that have been altered by human activity. It is
commonly found along roadsides and railway lines, on sandy ground,
wasteland and farmland, and in compacted urban areas.
It is widely
distributed across the southern United States, parts of Africa and
southern Europe. In Spain, for example, it is widespread in areas such
as Andalusia, Catalonia and the Valencian Community, and notably on the
central and western islands of the Canary Islands (Tenerife, Gran
Canaria, La Palma, El Hierro and La Gomera), where it is classified as a
non-invasive introduced species.
