Description:

Native to Florida, this species is an exciting flower for the garden as well as naturalizing with its exquisite violet blue flowers in spring; not actually a grass, but it is a close cousin to the familiar garden iris; divide clumps every 2 to 3 years

Ornamental Features

Blue-eyed Grass has masses of beautiful violet star-shaped flowers with blue overtones, lemon yellow eyes and lavender veins at the ends of the stems from early to late spring, which are most effective when planted in groupings. Its glossy narrow leaves remain dark green in color throughout the season.

Landscape Attributes

Blue-eyed Grass is an herbaceous perennial with an upright spreading habit of growth. 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 is a relatively low maintenance plant, and should not require much pruning, except when necessary, such as to remove dieback. It is a good choice for attracting bees and butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Self-Seeding

Blue-eyed Grass is recommended for the following landscape applications;

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

Planting & Growing

Blue-eyed Grass will grow to be about 10 inches tall at maturity, with a spread of 12 inches. Its foliage tends to remain low and dense right to the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 8 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 does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It may require supplemental watering during periods of drought or extended heat. It is not particular as to soil pH, but grows best in sandy soils. It is somewhat tolerant of urban pollution. This species is native to parts of North America. It can be propagated by division.

Blue-eyed Grass is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers against which the larger 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.
