| Poa trivialis | |
Poa trivialis (rough bluegrass;UK:rough-stalked meadow-grass [1] or rough meadow-grass [2] ), is a perennial plant regarded in the US as an ornamental plant. It is part of the grass family.
It is very common in meadows and pastures throughout Britain. Its preferred habitat is moist, sheltered places. Its herbage is plentiful and fairly nutritious, though not as much as Poa annua or Poa pratensis . It is useful for grazing on heavy and damp soil. It also copes well with the polluted atmosphere of towns and cities. It is in flower from June onwards throughout the summer.
It is often considered a weed of golf courses. It is an invasive species in the Great Lakes region and was first sighted in 1843. [3]
It has short stolons. The leaves are broad and tapering, and the sheathes are very rough. It has shiny leaves like Lolium perenne and crested dog's-tail. [4]
They have pointed ligules 4–10 mm (3/16 – 3/8 in.) long. Compare to annual meadow grass Poa annua which is silvery and pointed, and common meadow grass Poa pratensis which is short and blunt.
The roughish, slender stem grows 30 to 60 cm (1 to 2 ft.) high. Compare with smooth meadow grass Poa annua which has a smooth stem. The panicle is green and 15 cm (6 in.) long. The spikelets are egg-shaped.
It has a loose, whorled green panicle, much branched, 15 cm (6 in.) long.
It is also called Orcheston grass, after a village on Salisbury Plain. [5]
The food plant of the caterpillars of small heath (Coenonympha pamphilus), meadow brown (Maniola jurtina), gatekeeper (Pyronia tithonus) butterflies; common sun beetle ( Amara aenea ) – adults feed on the developing seeds, Eupelix cuspidata of the leafhopper family, and Myrmus miriformis a grassbug – feeds on young blades and developing seeds.
It is parasitised by grass mildew Blumeria graminis , which causes a white, powdery mildew on it.
Forage is a plant material eaten by grazing livestock. Historically, the term forage has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage.
Timothy is an abundant perennial grass native to most of Europe except for the Mediterranean region. It is also known as timothy-grass, meadow cat's-tail or common cat's tail. It is a member of the genus Phleum, consisting of about 15 species of annual and perennial grasses.
Alopecurus pratensis, known as the meadow foxtail or the field meadow foxtail, is a perennial grass belonging to the grass family (Poaceae). It is native to Europe and Asia.
Poa pratensis, commonly known as Kentucky bluegrass, smooth meadow-grass, or common meadow-grass, is a perennial species of grass native to practically all of Europe, North Asia and the mountains of Algeria and Morocco. Although the species is spread over all of the cool, humid parts of the United States, it is not native to North America. The Spanish Empire brought the seeds of Kentucky bluegrass to the New World in mixtures with other grasses. In its native range, Poa pratensis forms a valuable pasture plant, characteristic of well-drained, fertile soil. It is also used for making lawns in parks and gardens and has established itself as a common invasive weed across cool moist climates like the Pacific Northwest, and Northeastern United States. When found on native grasslands in Canada, for example, it is considered an unwelcome exotic plant, and is indicative of a disturbed and degraded landscape.
Festuca (fescue) is a genus of flowering plants belonging to the grass family Poaceae. They are evergreen or herbaceous perennial tufted grasses with a height range of 10–200 cm (4–79 in) and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass (Lolium), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus Festuca into the genus Lolium, or alternatively into the segregate genus Schedonorus.
Poa is a genus of about 570 species of grasses, native to the temperate regions of both hemispheres. Common names include meadow-grass, bluegrass, tussock, and speargrass. Poa is Greek for "fodder". Poa are members of the subfamily Pooideae of the family Poaceae.
Molinia caerulea, known by the common name purple moor-grass, is a species of grass that is native to Europe, west Asia, and north Africa. It grows in locations from the lowlands up to 2,300 m (7,546 ft) in the Alps. Like most grasses, it grows best in acid soils, ideally pH values of between 3.5 and 5, however, it can continue to live under more extreme conditions, sometimes to as low as 2. It is common on moist heathland, bogs and moorland throughout Britain and Ireland. Introduced populations exist in northeastern and northwestern North America.
Poa annua, or annual meadow grass, is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. This grass may have originated as a hybrid between Poa supina and Poa infirma.
Festuca pratensis, the meadow fescue, is a perennial species of grass, which is often used as an ornamental grass in gardens, and is also an important forage crop.
Cynosurus cristatus, the crested dog's-tail, is a short-lived perennial grass in the family Poaceae, characterised by a seed head that is flat on one side. It typically grows in species rich grassland. It thrives in a variety of soil types but avoids the acid and calcareous extremes of pH, and prefers well drained soils. It may be grown as an ornamental plant.
Arrhenatherum elatius, with the common names bulbous oat grass, false oat-grass, tall oat-grass, tall meadow oat, onion couch and tuber oat-grass, is a species of perennial grass, native to Europe, western Asia, and northern Africa.
British NVC community MG4 is one of the mesotrophic grassland communities in the British National Vegetation Classification system. It is one of four such communities associated with well-drained permanent pastures and meadows.
Festuca rubra is a species of grass known by the common name red fescue or creeping red fescue. It is widespread across much of the Northern Hemisphere and can tolerate many habitats and climates. It is best adapted to well-drained soils in cool, temperate climates; it prefers shadier areas and is often planted for its shade tolerance. Wild animals browse it, but it has not been important for domestic forage due to low productivity and palatability. It is also an ornamental plant for gardens.
Agrostis capillaris, the common bent, colonial bent, or browntop, is a rhizomatous and stoloniferous perennial in the grass family (Poaceae). It is native to Eurasia and has been widely introduced in many parts of the world. Colonial bent grows in moist grasslands and open meadows, and can also be found in agricultural areas, roadsides, and invading disturbed areas.
Bromus sterilis is an annual or biennial species of bromegrass known as barren brome, poverty brome, and sterile brome.
Agrostis gigantea, known by its common names black bent and redtop, is a perennial grass of the Agrostis genus.
Poa compressa, the Canada bluegrass or flattened meadow-grass, is a perennial flattened meadow grass, similar to common meadow-grass, Poa pratensis. It is native to Europe but it can be found nearly worldwide as an introduced species. It grows in old wall tops, pavement cracks, dry stony grassland, and many types of wild habitat. It has a flattened stem, 23–30 cm tall, a close one sided panicle of grey green, with purple florets.
Poa infirma is a species of grass known by the common names early meadow-grass and weak bluegrass. It was first described from a specimen found in Colombia, but it is actually an introduced species in the Americas and is native to Europe. It grows in many types of habitat, including disturbed areas. It is very similar to Poa annua, which is probably a daughter species, and it is often mistaken for P. annua unless it is closely examined.
Elachista freyerella is a moth of the family Elachistidae that is found in all of Europe, except the Balkan Peninsula. It is also found in North America.
British NVC community OV12 is one of the open habitat communities in the British National Vegetation Classification system. It is one of eight arable weed and wasteland communities of fertile loams and clays.
