Characteristics

Flat Sedge is a low-growing plant that typically reaches a height of 6-12 inches (15-30 cm) and spreads by rhizomes to form dense clumps. The leaves are narrow, flat, and linear, with a distinctive V-shaped cross-section. The stems are triangular in cross-section and can vary in color from green to reddish-brown.

Its roots are adapted to absorb nutrients and oxygen from the water, which allows it to thrive in wetland environments. The plant also has a high tolerance for salt, which makes it well-suited to growing in brackish water.

Uses

Flat Sedge has a variety of uses, both ornamental and practical. In gardens and landscapes, it is often used as a groundcover or edging plant, thanks to its low-growing habit and attractive foliage. It is also a popular choice for rain gardens and other water features, as it can help to filter pollutants and improve water quality.

It is also adaptable to a wide range of soil types, from sand to clay. It can be grown in full sun to part shade, but will tolerate more shade in wetter environments.

Propagation of Flat Sedge is typically done through division or seed. If you are dividing an established clump, it is best to do so in the spring, just as new growth is starting to appear. To propagate by seed, collect the seeds in the fall and plant them in a prepared bed in the spring.
