Ornamental Features

Landscape Attributes

Hardy Pampas 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 plant will require occasional maintenance and upkeep, 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.

Hardy Pampas Grass is recommended for the following landscape applications;

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

Planting & Growing

Hardy Pampas Grass will grow to be about 6 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. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!

This plant should only be grown in full sunlight. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is not particular as to soil type or pH. 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.
