Description

Carex comosa is an attractive sedge with light-green foliage and a fountain-like, clumping form. The leaves are erect to gently arching, and grow up to a height of 2'. The flowering culms can extend another couple of feet above the foliage. The flowering spikelets are large when compared to most Carex - up to 2 1/2" long - attractive and conspicuous, and are shaped like a bottle brush, hence the often-used common name bottlebrush sedge.

Cultivation

Longhair sedge almost exclusively occurs in wetlands. It is well adapted to mucky soil and is typically found growing in boggy areas, wet ditches, and along pond and stream margins. It can withstand regular inundation, and is one of the most ornamental sedges for use in rain gardens. Clumps will slowly expand by means of short rhizomes. The root system is fibrous and dense, making this species a favorite option for soil stabilization and erosion control. The preference is full, to part-sun. Zones 4-10

Propagation

Propagate from seed or by clump division.

Additional Notes

The seeds are very attractive to many species of wetland birds. Very deer resistant.
