Carex x knieskernii

Knieskern's Sedge (Carex x knieskernii) is a rare species of sedge native to the eastern United States. It is a ornamental perennial grass-like plant that grows up to two feet tall. Its Green stems have flowering spikes of bronze-red, orange or creamy yellow. Its soft, thread-like foliage forms a dense, interwoven mat. Preferred habitats include wet meadows, swamps, shorelines, and open bogs. Insects are attracted to the sedge's fragrant flowers and pollen, offering rich sources of nectar and nutrition for pollinators. With its amazing adaptability and easycare habit, Knieskern's Sedge is a delightful choice for wildlife gardens, wetland restorations, and ponds.

watering

For best results, Sedge plants should be watered once a week to 10 days. Water the plants deeply so that the soil is thoroughly saturated, then allow the soil to dry out between waterings. Do not allow the soil to become soggy or waterlogged. When the soil feels dry to the touch, it is time to water the Sedge. During periods of excessive heat or when growing in container gardens, water more frequently to prevent the plants from drying out.

sunlight

Sedge (Carex x haematolepis) thrives best in partial to full sunshine. This plant species prefers at least 4 to 6 hours of sunshine each day in order to remain healthy and vigorous. It’s best to give it some morning sunshine and then afternoon shade in hotter climates. When planting sedge in areas with very hot and dry climates, it’s best to place it in a location that receives some afternoon shade. This plant species can tolerate full shade, but it may not perform as well and will likely have fewer flowers.

pruning

When pruning a Sedge (Carex x haematolepis) plant, it is important to prune back the foliage to the desired height in spring (March-April) or early fall (September). It is best to leave about 5 inches (12.7 cm) of foliage behind when pruning for appearance and health of the plant. Make sure to use sharpened pruning shears when pruning to ensure clean cuts that do not cause damage to the plant. Prune off any dead or discolored leaves, branches and other damaged parts of the plant. Additionally, remove any excess foliage that could overcrowd the plant or interfere with its growth. Pruning should be done when necessary, usually every 2 to 3 years.
