Round-Spike Brownish Sedge

Carex brunnescens subsp. sphaerostachya

Round-Spike Brownish Sedge (Carex brunnescens subsp. sphaerostachya) is an interesting and attractive species native to moist open to semi-shade habitats in temperate and boreal North America. Growing up to twice the height of many other sedges, its bright green, glossy leaf blades produce tawny-brown to chocolate-colored flower spikes in the summer and autumn. The densely packed spikes give the plant its common name, and it is especially noticeable when backlit. It is highly tolerant of exposure and grows best in soils that are slightly damp and well-drained. An understory plant, it provides excellent cover and habitat for wildlife.

watering

Watering Brownish Sedge (Carex brunnescens subsp. brunnescens) plants should be done consistently without oversaturation. In well-draining garden soil, it should be watered weekly, allowing the soil to dry out slightly between waterings. Water the plants at the soil level until the soil is fully saturated and provide enough water to moisten the entire root zone. In containers, Brownish Sedge (Carex brunnescens subsp. brunnescens) should be checked more often and watered when the soil feels dry to the touch. To prevent root rot, it is always best to water thoroughly and avoid letting the soil dry out too much.

sunlight

Brownish Sedge (Carex brunnescens subsp. brunnescens) prefers full sun to moderate shade for optimal growing conditions. For best results, 6 – 8 hours of sunshine each day is necessary. It also appreciates some afternoon shade in hotter, drier climates with intense direct sunlight. This plant will tolerate partial shade but may not reach its full potential in terms of both size and color. It also tends to be more drought-tolerant in full sun.

pruning

Brownish Sedge is best pruned in late winter or early spring before new growth begins. Most plants of this species will benefit from yearly pruning, although it is not necessary for established plants. When pruning Brownish Sedge, it is important to retain as much of the old foliage as possible and to remove only brown, damaged foliage and thin out areas that have too much growth. Pruning should be done lightly and precisely in order to maintain the natural form of the plant. Pruning should not be done so heavily that the original natural form of the plant is lost.
