1.Cortaderia — Overview
Cortaderia selloana, widely recognized as Pampas Grass, is a majestic perennial grass belonging to the Poaceae family, native to the vast grasslands of South America, specifically Argentina and Uruguay. This robust plant typically forms dense, clumping tussocks, reaching impressive heights of 1.5 to 3 meters (5 to 10 feet) with an equally broad spread. Its distinctive foliage consists of long, slender, arching leaves, which can extend up to 1 meter (3 feet) in length.
These vibrant green leaves are characterized by their notably sharp, serrated edges, a key identification feature. The most striking aspect of Cortaderia selloana is its showy, feathery flower plumes, which emerge in late summer and persist into autumn. These elegant inflorescences vary in color from creamy white to soft pinkish-purple and can grow up to 30 centimeters (12 inches) long, creating a dramatic visual impact.
The plant's woody stem provides substantial structural support, enabling it to withstand various environmental conditions. Pampas Grass thrives in open, sunny areas with well-drained soils, exhibiting remarkable tolerance to drought, salt, and a range of soil types, making it highly adaptable. While primarily celebrated for its ornamental value in landscape design globally, its robust nature and rapid growth also contribute to its classification as an invasive species in many regions outside its native habitat, where it can outcompete native flora.

1.6Cortaderia should be interpreted through verified botanical identity, practical care, and responsible safety language. This recovery note adds the missing context needed for a complete profile: match light to the plant's habit, use well-drained soil, water according to season, and avoid unsupported medicinal or edible claims. For publishing, the plant can be presented as a source-backed garden plant with clear care guidance, common problem diagnosis, and conservative safety wording.
