How to Grow Pampas Grass in Containers

pampas image by Hubert from

Pampas grass (Cortaderia selloana) is an ornamental grass growing in a cluster with a long flowering blade shooting from the center. The long stem is feathering in appearance and stores seeds that are released when the perennial goes into the dormancy period. Uncut Pampas grass clusters grow over 6 feet tall. While traditionally grown outdoors for privacy or central focal point of a landscape design, frequently trimmed Pampas grass can grow in containers for patios, decks or indoors.

Line the bottom of a 10-gallon potting container with small pebbles or rocks to provide additional drainage for the Pampas grass.

Fill the container 3/4 full with potting soil. Rake the surface with a fork. Scatter a small handful of Pampas grass seeds in the center of the container. Cover with 1/4-inch of dirt. Water until the surface is moist but not wet.

Place the container in a south-facing window. Use a regular spray bottle to lightly mist the soil daily until the seeds germinate.

Water the seedlings weekly, once they have sprouted. Allow seedlings to reach approximately 24 inches prior to trimming.

Trim the Pampas grass as needed to control height for the container location.

Fast Does Pampas Grass Grow?

Pampas grass, also known as Cortaderia selloana, is native to the moist South American grasslands, known also as the pampas. The fast-growing grass can live in almost any habitat, but it grows especially well in rich soil and mild climates. Since it can grow 6 to 10 feet tall, each tussock or clump should be given plenty of space between it and other plantings. Large, flowering stalks range in color from white, yellow and pink. Pampas grass is a perennial. The plant goes dormant during the winter and resumes growth in the spring. Flowering occurs primarily in late summer. Plants prefer full sun and rich, well-drained soil. Larger plants should be removed using heavy machinery.


Place containers outdoor to create a privacy barrier for patios or a focal point for a deck.


Pampas grass blades are notorious for their sharp edges. Wear gardening gloves while trimming.
