Cortaderia selloana

Pampas Grass

Cortaderia selloana, commonly known as Pampas Grass, is a large, warm-season ornamental grass valued for its bold size and dramatic, feathery plumes. Long, arching green leaves form a dense clump in spring and summer, followed by tall, showy plumes in late summer to fall that emerge silvery-white (sometimes pinkish) and persist into winter, providing strong vertical interest and texture in the landscape.

Features & Landscape Uses


Large, dramatic plumes for late-season interest



Bold focal point or screening plant



Strong vertical and textural impact



Effective in mass plantings or large landscapes




Care
Cut back hard in late winter to early spring before new growth emerges (wear gloves due to sharp leaf edges). Plant in a protected location in colder climates, as winter hardiness can be limited. Prefers full sun and well-drained soil. Can be divided in spring if needed.
