Agrostis scabra is a common species of grass known by the common names hair grass, [2] rough bent, [3] rough bent grass, [2] winter bent grass, [2] and ticklegrass. [4] A tumbleweed, [4] [5] it is a bunchgrass native to Asia and much of North America, and widely known elsewhere as an introduced species.
It occurs in most of the United States except parts of the Southeast and in most of Canada except for the farthest northern regions. It can be found in Mexico and California, and across Alaska to far eastern Asia as far south as Korea. [6]
It is resident in a great variety of habitats, from warm coastal valleys to the alpine climate of high mountain ranges. It has been observed on cliffs, in forests, at forest edges, in meadows and fields, and at the shores of rivers and lakes. [7]
Agrostis scabra is a perennial bunchgrass growing mainly upright in form to heights of 6–39 in (15–99 cm), but reaching as high as 50 in (130 cm). It has been found growing as high as 12,000 ft (3,658 m) in Colorado. [8] The leaves are rough with tiny hairs and up to about 14 centimeters long. The inflorescence breaks off of the plant at maturity and is dispersed by wind. The plant is often confused with Agrostis hyemalis , but Agrostis scabra tends to flower later in the year. [8]
The tolerance of this grass to alpine climates makes it a good plant to use in revegetating disturbed land in such regions. [8] It is known to respond to burning with increased growth. [7] It is known to spring up on sites where few other plants can grow, such as abandoned coal mines and soils polluted with sulfur, copper, and nickel. [8] Prior to flowering, cattle, sheep, and horses readily consume it; it is also occasionally consumed by wild animals and after flowering by livestock. [8]
Festuca rubra is a species of grass known by the common name red fescue, creeping red fescue or the rush-leaf 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.
Agrostis exarata is a species of grass known by the common names spike bentgrass, spike bent, Pacific bentgrass, and spike redtop. It is native to western North America from Texas to the Aleutian Islands.
Danthonia intermedia is a species of grass known by the common names timber oatgrass, intermediate oatgrass, and mountain wild-oat grass. This clumping erect perennial grass is native to North America, where it is widespread across most of Canada and along the western United States into California. It is a plant of the plains as well as forested, mountainous, alpine environments.
Agrostis gigantea, known by its common names black bent and redtop, is a perennial grass of the Agrostis genus.
Calamagrostis rubescens is a species of grass known by the common name pinegrass.
Agrostis elliottiana is a species of grass known by the common name Elliott's bent grass.
Agrostis pallens is a species of grass known by the common name seashore bentgrass.
Poa glauca is a species of grass known by the common names glaucous bluegrass, glaucous meadow-grass and white bluegrass. It has a circumboreal distribution, occurring throughout the northern regions of the Northern Hemisphere. It is also known from Patagonia. It is a common grass, occurring in Arctic and alpine climates and other areas. It can be found throughout the Canadian Arctic Archipelago in many types of habitat, including disturbed and barren areas.
Agrostis perennans, the upland bentgrass, upland bent, or autumn bent, is a species of flowering plant in the grass family, Poaceae.
Ptilagrostiella kingii is a species of grass known by the common names Sierra false needlegrass and King's ricegrass. It is the sole species in genus Ptialgrostiella. It is a perennial native to central and eastern California and to Tamaulipas in northeastern Mexico. In California it is found in the high mountains of the Sierra Nevada, where it grows in meadows and near streams in subalpine and alpine climates.
Setaria verticillata is a species of grass known by the common names hooked bristlegrass, rough bristle-grass and bristly foxtail. It is native to Europe, but it is known on most continents as an introduced species and often a noxious weed. It is a hardy bunchgrass which grows in many types of urban, cultivated, and disturbed habitat. It is a weed of many types of agricultural crops, growing in vineyards and fields. Herbicide-resistant strains have been noted.
Sporobolus cryptandrus is a species of grass known as sand dropseed. It is native to North America, where it is widespread in southern Canada, most of the United States, and northern Mexico.
Sporobolus flexuosus is a species of grass known by the common name mesa dropseed. It is native to western North America, where it can be found in the deserts and woodlands of the Southwestern United States and Northern Mexico.
Sporobolus vaginiflorus is a species of grass known by the common names poverty grass, poverty dropseed, and sheathed dropseed.
Thalictrum alpinum is a species of flowering plant in the buttercup family known by the common names alpine meadow-rue and arctic meadow-rue. It is native to Arctic and alpine regions of North America and Eurasia, including Alaska, northern Canada, and Greenland, and it occurs in cold, wet, boggy habitats in high mountains farther south.
Townsendia condensata is a species of flowering plant in the family Asteraceae known by the common names cushion Townsend daisy and cushion townsendia. It is native to North America where it is known from many scattered occurrences in the mountains of the western United States and Alberta in Canada. It is mainly limited to the alpine climates of high mountain peaks, where it grows in meadows, tundra, and barren, rocky talus. It grows alongside other alpine plants such as Eriogonum androsaceum.
Agrostis canina, the velvety bentgrass, brown bent or velvet bent, is a species of grass in the family Poaceae.
Danthonia compressa is a species of grass known by the common names mountain oatgrass, flattened oatgrass, and slender oatgrass.
Hesperostipa spartea, formerly Stipa spartea, is a species of grass known by the common names porcupine grass, western porcupine grass, short-awn porcupine grass, porcupine needlegrass, and big needlegrass. It is native to North America, where it is widespread from British Columbia to Ontario in Canada and through the central and Great Lakes regions of the United States.
