Pampas Grass in the Landscape

Pampas grass is a hard-working landscape plant. Use it to create a living screen or a border backdrop by planting three to five plants together. Pampas grass is good for erosion control and stabilizing stream banks. Or plant it in landscape beds as a focal point plant. It offers multiple seasons of interest as its white plumes develop and then age to a tawny brown. Pampas grass can also be grown in containers. In Zones 6 and below grow pampas grass in large containers and overwinter it in a greenhouse or heated garage.

Pampas Grass Must-Knows

Pampas grass grows best in full sun and well-drained soil. It will tolerate light shade, but dense shade will cause it to become floppy. Once established pampas grass is drought tolerant and deer resistant. It has few pest problems and tolerates salt spray, making it an ideal plant for coastal landscapes.

Prune pampas grass in late winter to remove the previous year's foliage and make way for new growth. Power hedge shears are often the best tool for pruning the plant's dense growth at ground level. Pampas grass has sharp blades, so wear a long-sleeve shirt and jeans or slacks to protect your skin.

Drying Plumes

The flowers of pampas grass are prized for dried floral arrangements. Harvesting and drying your own flowers is simple. Cut the flowers as soon as they fully emerge but before they are mature and shedding. Let the stems dry in a cool, dark place. After the stems are dry, spray them with a light coat of hairspray to prevent shedding.
