What is Pampas Grass?

Pampas grass (Cortaderia selloana) is an ornamental grass that is native to South America. Its name comes from the pampas, or grasslands, of Argentina, Uruguay and Brazil. This evergreen perennial grows in clumps that can reach up to 12 feet (3.7 m) high and 10 feet (3 m) wide. The blades of the pampas grass are sharp and can grow up to 6 feet (1.8 m) long. The flowers of the pampas grass are white and resemble feathers. They bloom in the late summer and early fall.

The Benefits of Pruning Pampas Grass

Pampas grass is a beautiful and versatile ornamental grass that can be used in a variety of landscapes. Pampas grass is known for its tall, feathery plumes that can reach up to 10 feet in height. While pampas grass is a fairly low-maintenance plant, it does require periodic pruning in order to maintain its attractive appearance and to prevent it from becoming overgrown.

Pampas grass (Cortaderia selloana) is a clump-forming grass that typically grows 6 to 12 feet (1.8 to 3.7 m) tall and 6 to 8 feet (1.8 to 2.4 m) wide, although it can reach heights of up to 20 feet (6 m) in the right conditions. The plant’s large, silvery-white plumes rise above its bluish-green leaves from mid-summer through fall and persist into winter, providing interest in the garden when few other plants are in bloom.

Pampas grass can grow up to 10 feet tall and just as wide, making it a dramatic addition to any landscape. Although pampas grass is relatively low maintenance, it does require some pruning to look its best.

Pruning pampas grass in early spring (before new growth begins) will help prevent it from getting too big for its space. Start by removing any dead or damaged blades of grass with pruning shears. Then, use a sharp knife or pair of scissors to cut the remaining blades of grass back to about 6 inches tall. As new growth emerges, keep an eye on the plant and trim back any straggly blades to maintain a neat appearance.

In addition to keeping pampas grass tidy, regular pruning will also help promote new growth and extend the plant’s lifespan. With proper care, pampas grass can live for 10-20 years or more!
