Ornamental Features

Its pointy leaves remain green in color throughout the season.

Landscape Attributes

Artist Blue Flossflower is a dense herbaceous annual with a mounded form. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.

This plant will require occasional maintenance and upkeep. Trim off the flower heads after they fade and die to encourage more blooms late into the season. It is a good choice for attracting butterflies 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.

Artist Blue Flossflower is recommended for the following landscape applications;

  • Mass Planting
  • Border Edging
  • General Garden Use
  • Container Planting
  • Hanging Baskets

Planting & Growing

Artist Blue Flossflower will grow to be about 10 inches tall at maturity, with a spread of 12 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 8 inches apart. Its foliage tends to remain low and dense right to the ground. 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 plant should be grown in a location with partial shade or which is shaded from the hot afternoon sun. It does best in average to evenly moist conditions, but will not tolerate 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 particular variety is an interspecific hybrid. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Artist Blue Flossflower is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers against which the thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
