The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus Carex with over 2,000 species.
Ornamental grasses are grasses grown as ornamental plants. Ornamental grasses are popular in many colder hardiness zones for their resilience to cold temperatures and aesthetic value throughout fall and winter seasons.
Carex is a vast genus of more than 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges. Other members of the family Cyperaceae are also called sedges, however those of genus Carex may be called true sedges, and it is the most species-rich genus in the family. The study of Carex is known as caricology.
Carex chordorrhiza, commonly called creeping sedge or string sedge, is a species of perennial plant in the family Cyperaceae with Holarctic distribution growing in acidic bogs.
Carex nigra is a perennial species of plants in the family Cyperaceae native to wetlands of Europe, western Asia, north Africa, and eastern North America. Common names include common sedge, black sedge or smooth black sedge. The eastern limit of its range reaches central Siberia, Turkey and probably the Caucasus.
Carex pauciflora, known as few-flowered sedge, is a perennial species of sedge in the family Cyperaceae native to bogs and fens in cool temperate, subarctic, and mountainous regions of the Northern Hemisphere. The specific epithet pauciflora refers to the Latin term for 'few flowered'.
Carex comosa is a species of sedge known as longhair sedge and bristly sedge. It is native to North America, where it grows in western and eastern regions of Canada and the United States, and parts of Mexico. It grows in wet places, including meadows and many types of wetlands. Tolerates deeper water than most common species and is good for retention basins. This sedge produces clumps of triangular stems up to 100 or 120 centimeters tall from short rhizomes. The inflorescence is up to 35 centimeters long and has a long bract which is longer than the spikes. It is a cluster of several cylindrical spikes. The scales over the fruits taper into long, thin awns.
Carex rossii, commonly known as Ross's sedge, is a hardy species of sedge that is often a pioneer species in areas with little or no established vegetation, or in places where disturbance has occurred. Ross's sedge grows in a variety of habitats throughout much of western North America, from Alaska to Ontario, south to New Mexico and California. It flowers in May and June.
Carex spissa is a species of sedge known by the common name San Diego sedge. It is native to the southwestern United States in California, Arizona, and New Mexico, and far northern Mexico. It grows in wet places such as seeps and streambanks, sometimes on serpentine soils. This sedge looks somewhat like a cattail. It produces angled stems easily exceeding a meter in height surrounded by leathery green to reddish leaves up to about 1.2 meters long. The inflorescence is up to 80 centimeters long, with many long reddish brown flower spikes, each holding up to 300 developing fruits.
Carex pensylvanica is a species of flowering plant in the sedge family commonly called Pennsylvania sedge. Other common names include early sedge, common oak sedge, and yellow sedge.
Carex leptopoda, also known as slender-footed sedge and short-scale sedge, is a tussock-forming perennial in the family Cyperaceae. It is to Western Canada, United States, and Mexico.
Carex davisii, known as Davis' sedge or awned graceful sedge, is a species of Carex native to North America. It is listed as an endangered, threatened, or species of concern across much of edge of its range. It was named in the 1820s by Lewis David de Schweinitz and John Torrey in honor of Emerson Davis (1798–1866), a Massachusetts educator and "enthusiastic student of the genus" Carex.
Carex viridula, known as little green sedge, green sedge, or greenish sedge, is a small flowering plant native to North America, Europe, Asia, and Morocco.
Carex juniperorum, the juniper sedge, is a perennial flowering plant native to North America, first described by botanist William J. Crins in 1993. C. juniperorum is in the Cyperaceae (sedge) family, and is closely related to C. jamesii and C. willdenowii. It is commonly called juniper sedge as it is often seen growing in areas with red cedar, though the presence of cedar is not necessarily a requirement for it to grow.
Carex deweyanaDewey's sedge, short-scale sedge, is a species of sedge native to Canada and the United States.
Carex peckii, Peck's sedge, Peck's oak sedge, or white-tinged sedge, is a species of sedge native to Canada and the United States.
Carex bonplandii, Bonpland's sedge, is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to southern parts of Mexico, parts of Central America and northern parts of South America.
Carex crus-corvi, the raven's foot sedge or crowfoot sedge, is a species of flowering plant in the family Cyperaceae. It is native to southern Ontario in Canada, and the central and southeastern United States, and it has been introduced to Belgium. A perennial reaching 90 cm (3 ft) and hardy to USDA zone 4, it is an obligate wetland species found in a wide variety of such habitats.
