Ornamental Features

Blue Fountain Switch Grass features airy plumes of tan flowers with chartreuse overtones rising above the foliage in late summer. Its attractive grassy leaves emerge bluish-green in spring, turning steel blue in color. As an added bonus, the foliage turns gorgeous shades of tan and in the fall. The brown seed heads are carried on showy plumes displayed in abundance from late summer to mid fall.

Landscape Attributes

Blue Fountain Switch Grass is an 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 cut back to the ground in late winter before active growth resumes. It has no significant negative characteristics.

Blue Fountain Switch Grass is recommended for the following landscape applications;

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

Planting & Growing

Blue Fountain Switch Grass will grow to be about 6 feet tall at maturity, with a spread of 6 feet. It tends to be leggy, with a typical clearance of 1 foot from the ground, and should be underplanted with lower-growing perennials. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 15 years.

This plant does best in full sun to partial shade. It is very adaptable to both dry and moist locations, and should do just fine under typical garden conditions. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil type, but has a definite preference for alkaline soils, and is able to handle environmental salt. It is somewhat tolerant of urban pollution. This is a selection of a native North American species. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
