This variety is a ground-covering, evergreen, grass-like sedge that spreads like a carpet, with soft arching foliage that is deep dark green; grows well in shade to part sun, in humus rich, evenly moist soil; great for massing or containers
Irish Green Sedge is primarily valued in the garden for its broadly spreading habit of growth. Its attractive grassy leaves remain dark green in color throughout the year.
Irish Green Sedge is an herbaceous evergreen perennial grass with a ground-hugging 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 cleaned up in early spring before it resumes active growth for the season. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.
Irish Green Sedge is recommended for the following landscape applications;
- Mass Planting
- Border Edging
- General Garden Use
- Naturalizing And Woodland Gardens
- Container Planting
Planting & Growing
Irish Green Sedge will grow to be about 16 inches tall at maturity, with a spread of 24 inches. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years. As an evegreen perennial, this plant will typically keep its form and foliage year-round.
This plant performs well in both full sun and full shade. It prefers to grow in moist to wet soil, and will even tolerate some standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. 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.
Irish Green Sedge is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
