Pampas grass (Cortaderia selloana) grows wild in its native habitat in Brazil, Argentina and Chile and is hardy in U.S. Department of Agriculture plant hardiness zones 8 through 10. This ornamental grass grows large, reaching up to 12 feet tall and spreading 4 to 6 feet wide. According to the Missouri Botanical Garden, pampas grass is one of the most frequently planted ornamental grass varieties. The dense tussocks of arching green leaves are topped with large fluffy feathery plumes.
The silver white plumes, sometimes tinted pink, are the flowers or inflorescences of this grass plant. The fluffy dense panicles reach 1 to 4 feet long, increasing the overall height of the pampas grass clump. The plumes produce a fountain-like shape and appear from fall through late winter.
Use of Plumes
Female pampas grass plants produce larger and showier plumes. Male plumes are thinner and more elongated than those produced by the females. The plumes work well in cut flower bouquets and as as dried blossoms. Cut the plumes as soon as they open to create hardy dried flowers. Many dried plumes are dyed bright jewel colors.
Pampas grass flowers best when grown in full sun exposure, but it will tolerate light shade. Do not keep the soil too wet. Pampas grass grows in average moist or dry soil. Each year in the late winter, cut the leaves down to the ground to make room for new spring growth. When the amount and size of the plumes decreases or the center of the clump begins to die out, the pampas grass is overcrowded. Dig the clump up and divide the plant into smaller clumps in the late winter or early spring.
Pampas grass grows aggressively in dry frost-free climates. Female plants produce many seeds, but only seeds fertilized by a nearby male plant will be viable. These plants self-seed but the seedlings produced do not possess the same characteristics as the parent plants. Once the wind scatters the seeds, the seedlings naturalize throughout the environment and crowd out native plants. If growing an established pampas grass clump, keep the plumes cut back to control the release of seeds.
