description_en: Genus of about 100 species of mainly evergreen, creeping, mat-forming perennials and semi-prostrate subshrubs, widely distributed over the S. hemisphere, most from open habitats at high altitudes. Acaenas are cultivated for their variously coloured, narrowly oblong-ovate, pinnate leaves, and petalless flowers. These are produced in stalked spikes or dense, ovoid or spherical heads, which develop into colourful, spiny burrs in mid- or late summer. The prostrate stems root where they touch the ground and rapidly form dense mats of foliage. The burrs may be a nuisance to pets. A. microphylla ’Kupferteppich’ is an effective and restrained rock garden plant. Other acaenas are good -although invasive - ground-cover plants.
