Perennial - Sedges

Sedges

Botanical Name

:

Varies by species, common genera include Carex and Cyperus.

Plant Type

:

Perennial grass-like plants (though not true grasses, they belong to the Cyperaceae family).

Seasons

:

Year-round (evergreen or semi-evergreen, depending on species and climate)

Sun Level

:

Full sun to full shade (varies by species)

Soil Type

:

Moist, well-draining soil, some species tolerate wet or boggy conditions, while others prefer drier soils.

Germination

:

Propagates through division, seeds, or rhizomes. Seeds may take several weeks to germinate.

P.H. Level

:

Slightly acidic to neutral (5.5–7.0)

Water/Irrigation

:

Many sedges require consistent moisture levels, especially those found in wetland habitats. However, some species are more drought-tolerant than others.

Fertilization

:

Not necessary unless using organic fertilizers to maintain soil richness.

Habit

:

Clumping, spreading, or arching, depending on the species.

Final Plant Height

:

6–36 inches (15–90 cm), depending on variety.

Spread

:

12–36 inches (30–90 cm)

Spacing

:

12–18 inches apart for ground cover; wider for specimen planting. Spacing should allow enough room for spreading without overcrowding—about the same width as its mature spread.

Flowers

:

Typically greenish-yellowish spikes borne on stalks above foliage. They have separate male and female flowers within spikelets.

Attracts

:

Some species attract pollinators; birds may eat the seeds.

Uses

:

Ground cover, erosion control, rain gardens, borders, container planting, wetland restoration.

Companions

:

Hostas, ferns, astilbes, coral bells, woodland perennials

Pruning

:

Cut back dead or tattered foliage in late winter or early spring.

Toxicity

:

Non-toxic to humans and pets

Pests

:

Generally pest-free but may attract aphids or grasshoppers.

Diseases

:

Rarely affected by disease, though root rot may occur in overly wet conditions.

Fun Fact

:

Unlike true grasses, sedges have triangular stems—a key feature captured in the phrase “Sedges have edges.”

Additional Info

:

With over 2,000 species worldwide, sedges can be found in diverse habitats, from woodlands to wetlands to alpine regions.
