The United States Department of Agriculture (USDA) is an executive department of the United States federal government that aims to meet the needs of commercial farming and livestock food production, promotes agricultural trade and production, works to assure food safety, protects natural resources, fosters rural communities and works to end hunger in the United States and internationally. It is headed by the secretary of agriculture, who reports directly to the president of the United States and is a member of the president's Cabinet. The current secretary is Tom Vilsack, who has served since February 24, 2021.
The Agricultural Research Service (ARS) is the principal in-house research agency of the United States Department of Agriculture (USDA). ARS is one of four agencies in USDA's Research, Education and Economics mission area. ARS is charged with extending the nation's scientific knowledge and solving agricultural problems through its four national program areas: nutrition, food safety and quality; animal production and protection; natural resources and sustainable agricultural systems; and crop production and protection. ARS research focuses on solving problems affecting Americans every day. The ARS Headquarters is located in the Jamie L. Whitten Building on Independence Avenue in Washington, D.C., and the headquarters staff is located at the George Washington Carver Center (GWCC) in Beltsville, Maryland. For 2018, its budget was $1.2 billion.
Natural Resources Conservation Service (NRCS), formerly known as the Soil Conservation Service (SCS), is an agency of the United States Department of Agriculture (USDA) that provides technical assistance to farmers and other private landowners and managers.
The United States National Agricultural Library (NAL) is one of the world's largest agricultural research libraries, and serves as a national library of the United States and as the library of the United States Department of Agriculture. Located in Beltsville, Maryland, it is one of five national libraries of the United States. It is also the coordinator for the Agriculture Network Information Center (AgNIC), a national network of state land-grant institutions and coordinator for the U.S. Department of Agriculture (USDA) field libraries.
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries in various forms. A plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 to 40 °F.
Andropogon gerardi, commonly known as big bluestem, is a species of tall grass native to much of the Great Plains and grassland regions of central and eastern North America. It is also known as tall bluestem, bluejoint, and turkeyfoot.
Celosia argentea, commonly known as the plumed cockscomb or silver cock's comb, is a herbaceous plant of tropical origin in the Amaranthaceae family from India and Nepal. The plant is known for its very bright colors. In India and China it is known as a troublesome weed.
Hair grass is a common name for several plants and can refer to:
Azolla filiculoides is a species of aquatic fern. It is native to warm temperate and tropical regions of the Americas, and has been introduced to Europe, North and sub-Saharan Africa, China, Japan, New Zealand, Australia, the Caribbean and Hawaii.
Iris lacustris, the dwarf lake iris, is a plant species in the genus Iris, subgenus Limniris and in the section Lophiris. It is a rhizomatous, beardless perennial plant, native to the Great Lakes region of eastern North America. It has lavender blue or violet-blue flowers, a very short stem and long fan-like green leaves. It is cultivated as an ornamental plant in temperate regions. It is closely related to Iris cristata.
Iris cristata is a species in the genus Iris, and is part of the subgenus of Limniris. It is a rhizomatous perennial plant, endemic to the eastern United States. It has pale lavender flowers with a white patch and orange or yellow crest. It is a close relative to Iris lacustris, the only other crested iris native to North America. It is cultivated as an ornamental plant in temperate regions.
Azolla cristata , the Carolina mosquitofern, Carolina azolla or water velvet, is a species of Azolla native to the Americas, in eastern North America from southern Ontario southward, and from the east coast west to Wisconsin and Texas, and in the Caribbean, and in Central and South America from southeastern Mexico (Chiapas) south to northern Argentina and Uruguay.
Dryopteris cristata is a perennial species of fern native to wetlands throughout the Northern Hemisphere. It is known as crested wood fern, crested buckler-fern or crested shieldfern. This plant is a tetraploid species of hybrid origin, one parent being Dryopteris ludoviciana and the other being the unknown, apparently extinct species, dubbed Dryopteris semicristata, which is also one of the presumed parents of Dryopteris carthusiana. D. cristata in turn is one of the parents of Dryopteris clintoniana, another fern of hybrid origin.
Rostraria is a genus of plants in the grass family, native primarily to Eurasia and North Africa with one species native to South America. Hairgrass is a common name.
Anoda cristata is a species of flowering plant in the mallow family known by many common names, including spurred anoda, crested anoda, and violettas. It is native to North and South America. It is known throughout the rest of the Americas as well as Australia as an introduced species and often a noxious weed. It has been found as a weed in Belgium. Naturally, it is often found near streams, in moist meadows, and in disturbed areas.
Leptochloa is a widespread genus of Asian, African, Australian, and American plants in the grass family.
Iris verna, the dwarf violet iris, is a species of flowering plant in the iris family (Iridaceae). It is endemic to the eastern United States from Maryland to Florida along the Atlantic Coast, west to Mississippi, and inland to Kentucky, Tennessee, and Ohio. It occurs in nutrient-poor acidic soils of open to semi-shaded woodlands.
Sagittaria cristata, the crested arrowhead, is a perennial herb growing up to 75 centimetres tall. The leaves are flat, long and narrow, not lobed, and up to 40 cm (16 in) long. The flowers are white.
The Cooperative State Research, Education, and Extension Service (CSREES) was an extension agency within the U.S. Department of Agriculture (USDA), part of the executive branch of the federal government. The 1994 Department Reorganization Act, passed by Congress, created CSREES by combining the former Cooperative State Research Service and the Extension Service into a single agency.
Trisetaria is a genus of plants in the grass family, native to Asia and to the Mediterranean region.
