Grown for its stiff upright blue-green foliage, this variety is well suited to garden beds and mixed containers; can be grown as a pond plant but is also quite drought tolerant when grown in the garden.
Blue Dart Rush is a dense herbaceous perennial grass with an upright spreading habit of growth. 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 cut back to the ground in late winter before active growth resumes. It has no significant negative characteristics.
Blue Dart Rush is primarily valued in the garden for its ornamental upright and spreading habit of growth. Its attractive grassy leaves remain bluish-green in colour with showy blue variegation throughout the season.
Blue Dart Rush will grow to be about 18 inches tall at maturity, with a spread of 12 inches. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a fast 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!
Blue Dart Rush 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 canvas of foliage 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.
