Pampas Grass

 

Pampas grass is commonly found in gardens and preserves in California, but it is actually from South America. Due to its preference for warm weather, it has been naturalized in different areas here.

It has quickly become a popular ornamental grass due to its tall height and iconic flower plumes that sway gracefully in the breeze.

Botanical name: Cortaderia selloana

Other names: White pampas grass

TABLE OF CONTENTS

Pampas Grass Appearance

Pampas grass is a 6-12 foot tall evergreen grass.

The plant grows in large clumps called tussocks that spread to 5 feet wide. The leaves are tall and thin and arch outwards. They are deep green and have sharp, serrated edges.

The flowering stalks are rigid, thicker, and taller than the grass blades. The flowers grow at the end of the stalks and are usually cream-colored, but some are pink, silver, or purple. Female flowers are shinier and fuller than male flowers.

Blooms are followed by numerous tiny seeds that depend on wind for pollination.

Pampas Grass Landscaping Tips

Adds movement and vertical interest to the garden.

Excellent for cut flowers. Use fresh in large vases or dry in floral arrangements and wreaths.

Tolerates frost and heat. Somewhat drought-tolerant.

Pampas grass is considered invasive in some parts of the country. Check with local experts and consider varieties such as “Pumila” that do not reseed.

Requires both female and male plants to reseed.

Sharp, serrated leaves. Handle with caution.

Prune in late winter. The entire clump can be cut back to a foot tall and keeps the plant manageable. Otherwise, remove dead leaves and stalks.

Yes. For best performance, plant in areas that receive morning sun and little afternoon sun. Add compost or fertilizer when planting it. Provide regular water during hot temperatures.

why cut back pampas grass?

Cutting pampas grass back to 1-2 feet will keep it manageable and hide the dead, brown leaves. The grass blades are very sharp and are more challenging to cut when fully grown (about 6-12 feet tall). The heavy pruning should be done in late winter when it is not actively growing.
