What is Pink Pampas Grass?
Pampas grass (Cortaderia selloana) is native to South America, specifically Brazil, Argentina, and Chile. It got its name from the Pampas Plains. This tough grass thrives in heat and plenty of bright sunlight. It grows quickly into a big, bold plant. Once established, the grass can grow an inch a day. A clump of pampas can expand to about eight feet wide, and up to 12 feet tall (there are shorter varieties, too). The plumes themselves grow between one and three feet in length. There are several varieties of pampas grass that Some big, some small, and a few are pink. Varieties like Rosea and Pink Feather showcase bright pink blooms. Other types of pampas grass plumes look white, silver, cream, or bluish-green. There’s even a purple one called Andean pampas grass that can grow up to 22 feet tall.

The extra fluffy pink pampas grass seed heads you might see used in homes and at events are from female plants. The plants can be either female or male, and each has distinctive plumes.

The only way to find out if a pampas grass plant is male or female is to wait for it to bloom.
