Holm's Rocky Mountain Sedge

Carex scopulorum

Also Known As - Mountain Sedge
Holm's Rocky Mountain Sedge (Carex scopulorum) is a perennial plant species native to western North America. It forms a low-growing, densely tufted clump of evergreen, dark green foliage. The leaves are very narrow and taper to an almost grasslike point. Its yellow-green flower spikes bloom in early summer, providing a spectacular display of flowers. It prefers full to partial sun and moist to wet soils. It is an excellent choice for erosion control, stream banks, and damp soils. This robust grass-like species will add texture and color to any garden refuge.

watering

For this species of plant, it is best to water it deeply and then allow the soil to become slightly dry between waterings. During the warmer summer months, it should be watered more frequently, roughly every week. During the winter months, when the plant is dormant, it should only be watered once every 2 to 3 weeks. During periods of extreme heat and drought, it may require watering more than once a week, depending on the temperatures and the condition of the soil.

sunlight

Holm's Rocky Mountain Sedge requires full sun for optimal growth. This species of plant should receive approximately 8-10 hours of sunlight each day during the growing season and less during winter. It grows best in warm weather and can tolerate temperatures of up to 90 degrees Fahrenheit. Holm's Rocky Mountain Sedge needs regular watering, especially during dry periods. When watering, make sure to keep the soil evenly moist and avoid over-watering.

pruning

Holm's Rocky Mountain Sedge should be pruned late in the season, usually after flowering has ceased in late summer or early fall. Pruning should be minimal, and should focus on removing any dead or dying foliage and thinning dense growth. To thin, simply remove the center shoots of the clump, leaving the outer, more vigorous shoots to grow. Pruning more than 25-30% of the shoots runs the risk of stressing the plant.
