Cortaderia selloana – Classic Pampas Grass
Cortaderia selloana is a bold, architectural ornamental grass renowned for its tall clumps of arching green foliage and spectacular feathery flower plumes that appear from late summer into autumn. Rising well above the foliage, the silky plumes add height, movement, and drama to the garden and remain attractive well into winter. Hardy, drought-tolerant once established, and highly impactful, pampas grass is ideal for large borders, specimen planting, and contemporary landscapes.
