Species Sedge

Sedge

Carex x subimpressa

Sedge (Carex x subimpressa) is a herbaceous perennial plant native to Japan and hardy in USDA zones 4-8. It forms an attractive, clumping mound of deep green, grass-like foliage, up to 16” tall. Its unique weeping feature adds texture to the garden. In late spring it bears panicles of small, pink-tinged flowers that attract pollinators. Best grown in part-shade and moist but well-drained soil, it is a great addition to rain gardens and damp areas. Sedge is also easy to care for, requiring minimal pruning and fertilizing, and it can be divided every 4-5 years for more plants.

watering

Sedge (Carex x spiculosa) should be watered deeply and infrequently, about 2 to 3 times per month. The soil should be kept constantly moist but not saturated. If the soil is allowed to dry out, Sedge will not survive. If tempertatures drop below 65 degrees Fahrenheit, the plant should be watered about every 2 weeks. In the summer months, when outside temperatures are higher than 65 degrees Fahrenheit, more frequent watering may be necessary.

sunlight

Sedge (Carex x spiculosa ) grows best in full sun to light shade, with up to 6 hours of direct sunlight per day. In areas with excessive heat, the plants may need some protection from the sun's rays. The amount of sunlight should be adjusted depending on the season. During periods of extreme heat, plants should be shaded from the midday sun. For optimal growth, the sedge should receive more sun during the cooler months.

pruning

Sedge (Carex x spiculosa) should be pruned once a year in the springtime, usually within the first few weeks. Pruning should be done to keep the plant neat and encourage healthy growth. Start by cutting off any dead or diseased shoots and removing them from the garden. Then, cut the stems back to their desired length. Height can range from 8 to 18 inches, depending on preference. Lastly, prune out any stems that are thin, weak, or thinning. Pruning promotes strong, healthy growth and can help the plant resist environmental stressors.
