Ornamental Features

Pampass Grass features airy plumes of silver hop-like flowers with a purple flare at the ends of the stems in late summer. The flowers are excellent for cutting. Its attractive grassy leaves are grayish green in color. As an added bonus, the foliage turns a gorgeous harvest gold in the fall. The fruit is not ornamentally significant.

Landscape Attributes

Pampass Grass is a dense herbaceous perennial grass with an upright spreading habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This is a relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season. It is a good choice for attracting birds to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Pampass Grass is recommended for the following landscape applications;

  • Accent
  • Mass Planting
  • Hedges/Screening
  • General Garden Use

Planting & Growing

Pampass Grass will grow to be about 5 feet tall at maturity extending to 12 feet tall with the flowers, with a spread of 8 feet. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 10 years.

This plant should only be grown in full sunlight. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is not particular as to soil pH, but grows best in sandy soils. It is highly tolerant of urban pollution and will even thrive in inner city environments. This species is native to parts of North America. It can be propagated by division.
