Description:

A smaller, finer textured selection, producing a clump of narrow, silver edged foliage that arches elegantly outward; cream plumes emerge, but barely rise above the foliage; prefers full sun, but tolerates some light shade

Ornamental Features

Silver Comet Pampas Grass's attractive spiny grassy leaves remain grayish green in colour with distinctive silver edges throughout the season on a plant with an arching habit of growth. It features subtle plumes of creamy white flowers held atop the stems from late summer to late fall. The flowers are excellent for cutting. The tan seed heads are carried on plumes from late fall to late winter.

Landscape Attributes

Silver Comet Pampas Grass is an herbaceous annual with a shapely form and gracefully arching foliage. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

This is a relatively low maintenance plant, and is best pruned in late winter once the threat of extreme cold has passed. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Invasive
  • Self-Seeding

Silver Comet Pampas Grass is recommended for the following landscape applications;

  • Accent
  • Mass Planting
  • General Garden Use
  • Naturalizing And Woodland Gardens
  • Container Planting

Planting & Growing

Silver Comet Pampas Grass will grow to be about 6 feet tall at maturity, with a spread of 6 feet. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. Although it's not a true annual, this fast-growing plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat. This is a dioecious species, meaning that individual plants are either male or female. Only the females will produce fruit, and a male variety of the same species is required nearby as a pollinator.

This plant should only be grown in full sunlight. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. 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 is a selected variety of a species not originally from North America. 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.

Silver Comet Pampas Grass is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
