The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large; botanists have described some 5,500 known species in about 90 genera – the largest being the "true sedges", 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 over 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 echinata is a species of sedge known by the common names star sedge and little prickly sedge.
Carex riparia, the greater pond sedge, is a species of sedge found across Europe and Asia. It grows in a variety of wet habitats, and can be a dominant species in some swamps. It is Britain's largest Carex, growing up to 130 cm tall, with glaucous leaves up to 160 cm long. It hybridises with a number of other Carex species, including the closely related Carex acutiformis – the lesser pond sedge. A variegated cultivar is grown as an ornamental grass.
Carex lacustris, known as lake sedge, is a tufted grass-like perennial of the sedge family (Cyperaceae), native to southern Canada and the northern United States. C. lacustris us an herbaceous surface-piercing plant that grows in water up to 50 cm (1.6 ft) deep, and grows 50–150 cm (1.6–4.9 ft) tall. It grows well in marshes and swampy woods of the boreal forest, along river and lake shores, in ditches, marshes, swamps, and other wetland habitat. It grows on muck, sedge peat, wet sand or silt, in filtered or full sunlight.
Carex archeri, known as Archer's sedge, is a species of sedge in the genus Carex, endemic to south-eastern Australia.
Carex kobomugi is a species of sedge, known as the Japanese sedge or Asiatic sand sedge, that lives in sandy coastal areas of eastern Asia, and has become an invasive species in the north-eastern United States.
Carex exilis, common name coastal sedge or meager sedge, is a species of grass-like plant in the Cyperaceae family. It is native to North America and Canada, with several disjunct populations from southern Canada to the Gulf Coast.
Carex careyana, commonly known as Carey's sedge, is a species of sedge found in the eastern United States and Ontario, Canada.
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 elata, is a species of tussock-forming, grass-like plant in the Cyperaceae family. It is native to all of Europe, the Atlas Mountains of Africa, Turkey, Iran and Central Asia.
Carex remota, the remote sedge, is a species in the genus Carex, native to Europe, the Atlas Mountains in Africa, and western Asia. It is a riparian forest specialist. It is known as one of the most frequently hybridizing species of Carex, forming hybrids with C. appropinquata, C. arenaria, C. brizoides, C. canescens, C. divulsa, C. echinata, C. elongata, C. leporina, C. otrubae, C. paniculata, and C. spicata.
Carex hostiana, the tawny sedge, is a species of flowering plant in the genus Carex, native to Europe and northeast Canada, and extinct in Massachusetts. It is a member of the Carex flava species complex.
Carex demissa is a species of sedge, native to Iceland, Macaronesia, all of Europe, and western Asia to the Himalayas and possibly Greenland. It has been introduced to eastern Canada, New Jersey, and Tasmania. It is a member of the Carex flava species complex.
Carex lepidocarpa, called the long-stalked yellow-sedge, is a species of flowering plant in the genus Carex, native to eastern Canada, Morocco, and most of Europe. It is a member of the Carex flava species complex.
Carex paui is a rare species of sedge, with a western Mediterranean distribution; Morocco, Algeria, Tunisia, Spain,, and Italy. Some authorities considered it a synonym of Carex laxula, but as that name was not validly published, Carex paui was the next available name.
Carex leersii, the grassland sedge or many-leaved sedge, is a widespread species of flowering plant in the family Cyperaceae. It is native to the Atlas Mountains in Africa, Europe, the Middle East, Central Asia, the Altai and the western Himalayas, and has been introduced to New Zealand. It is a member of the Carex muricata group, and prefers to grow in sunny, relatively dry locations.
