Pampas grass: Cortaderia sellonana

Pampas grass is grown for its distinctive silvery white plumes flushed with pink and held on very tall stems above narrow, arching leaves arranged in a loose mound. In fall, gray seed heads form in loose pyramidal clusters along the tip of the canes and persist through winter. Several cultivars with varying flower and leaf color and habit of this species are available; 'Sunningdale Silver' resists wind and rain best.

did you know?

Pampas grass is named for the vast plain in South America where it grows wild. The name pampas comes from a Quechua Indian word meaning "flat surface." The pampas extends from the Atlantic coast of central Argentina to the Andean foothills, north to the Gran Chaco and south as far as Patagonia.

general maintenance:

Cut out any flower stalks that fall over, or stake with a cat's cradle in early spring. In late winter or early spring, cut old stems and leaves to the ground before new growth emerges in spring. Divide regularly to prevent rampant growth.

pests/diseases:

Pampas grass is relatively pest and disease free.

how to sow/plant:

Choose a sunny site with moist, well-drained soil, and amend with well-rotted manure or compost. Set plants out in spring or fall at the same depth they were in pot, spacing at a distance equal to their mature spread. Water after planting, and mulch to conserve moisture.

water and fertilize:

Maintain soil moisture all season. Feed with an all-purpose fertilizer during active growth, following label directions.

garden hint:

Pampas grasses tend to be dioecious, meaning male and female are borne on separate plants. For the best flowers, select a female plant. Use care when working with this grass, because the leaves can easily cut hands and arms when staking or cutting once it has reached full size.
