Helianthus Maximiliani
''Helianthus maximiliani'' is a North American species of sunflower known by the common name Maximilian sunflower. This sunflower is named for Prince Maximilian of Wied-Neuwied, who encountered it on his travels in North America. ''Helianthus maximiliani'' is native to the Great Plains in central North America, and naturalized in the eastern and western parts of the continent. It is now found from British Columbia to Maine, south to the Carolinas, Chihuahua, and California. The plant thrives in a number of ecosystems, particularly across the plains in central Canada and the United States. It is also cultivated as an ornamental. Description A branching perennial herb, growing from a stout rhizome and reaches heights from . The slender, tall, erect stems and alternately-arranged leaves are covered in rough hairs. The lance-shaped leaves are narrow, pointed, folded down the midvein, and up to long on large plants. The flower heads are surrounded at the base by pointed green phy ...

Wind Cave National Park
Wind Cave National Park is an American national park located north of the town of Hot Springs in western South Dakota. Established on January 3, 1903 by President Theodore Roosevelt, it was the sixth national park in the U.S. and the first cave to be designated a national park anywhere in the world. The cave is notable for its calcite formations known as boxwork, as well as its frostwork. Approximately 95 percent of the world's discovered boxwork formations are found in Wind Cave. The cave is recognized as the densest cave system in the world, with the greatest passage volume per cubic mile. Wind Cave is the seventh longest cave in the world with of explored cave passageways () and the third longest cave in the United States. Above ground, the park includes the largest remaining natural mixed-grass prairie in the United States. Origin of name The passages in the park are said to "breathe" as air continually moves into or out of them, equalizing the atmospheric pressure o ...

Phyllaries
In botanical terminology, a phyllary, also known an involucral bract or tegule, is a single bract of the involucre of a composite flower. The involucre is the grouping of bracts together. Phyllaries are reduced leaf-like structures that form one or more whorls immediately below a flower head. Function Phyllaries provide protection to developing flowers and fruits. In the dandelion hybrid ''Taraxacum japonicum'' × ''officinale'', recurved phyllaries help defend the flowers from herbivory by slugs. They sometimes assist in the dispersal of fruits. The hooked phyllaries of burdock species ('' Arctium'') cling to the fur and feathers of animals, dispersing the seeds away from the parent plant ( exozoochory). Structure and arrangement Phyllary morphology is useful in plant identification as between species of the Asteraceae The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales ...

Plants Used In Native American Cuisine
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Wes Jackson
Wes Jackson (born 1936) co-founded the Land Institute with Dana Jackson. He is also a member of the World Future Council. Early life and education Jackson was born and raised on a farm near Topeka, Kansas. After earning a BA in biology from Kansas Wesleyan University, an MA in botany from the University of Kansas, and a PhD in genetics from North Carolina State University, Wes Jackson established and served as chair of one of the United States' first environmental studies programs at California State University, Sacramento. Jackson then chose to leave academia, returning to his native Kansas, where he founded a non-profit organization, The Land Institute, in 1976. The Land Institute is working to develop perennial grains, pulses, and oilseed-bearing plants to be grown in ecologically intensified, diverse crop mixtures under its Natural Systems Agriculture program. In tandem with these sustainable agriculture efforts, the Ecosphere Studies program seeks to change the way peo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salina, Kansas
Salina is a city in, and the county seat of, Saline County, Kansas, United States. As of the 2020 census, the population was 46,889. In the early 1800s, the Kanza tribal land reached eastward from the middle of the Kansas Territory. In 1858, settlers from Lawrence founded the Salina Town Company with a wagon circle, under constant threat of High Plains tribal attacks from the west. It was named for the salty Saline River. Saline County was soon organized around this township, and in 1870, Salina incorporated as a city. As the westernmost town on the Smoky Hill Trail, Salina boomed until the Civil War by establishing itself as a trading post for westbound immigrants, gold prospectors bound for Pikes Peak, and area American Indian tribes. It boomed again from the 1940s-1950s when the Smoky Hill Army Airfield was built for World War II strategic bombers. It is now a micropolis and regional trade center for North Central Kansas. Higher education institutions includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Land Institute
The Land Institute is an American nonprofit research, education, and policy organization dedicated to sustainable agriculture, based in Salina, Kansas. Their goal is to develop an agricultural system based on perennial crops that "has the ecological stability of the prairie and a grain yield comparable to that from annual crops". History The institute was founded on in 1976 by plant geneticist and MacArthur "genius grant" recipient Wes Jackson along with Dana Jackson, who has worked with the Land Stewardship Project in Minnesota. The Land Institute promotes "natural systems agriculture" through plant breeding. Using selective breeding and other techniques, they are working to domesticate wild perennials. The organization's concept of developing perennial crops is modeled after the ecological design of prairies, which are known for their soil quality, deep root systems, and self-sufficiency. In an interview, Wes Jackson called the concept "an inversion of industrial agricultu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sioux
The Sioux or Oceti Sakowin (; Dakota: /otʃʰeːtʰi ʃakoːwĩ/) are groups of Native American tribes and First Nations peoples in North America. The modern Sioux consist of two major divisions based on language divisions: the Dakota and Lakota; collectively they are known as the Očhéthi Šakówiŋ ("Seven Council Fires"). The term "Sioux" is an exonym created from a French transcription of the Ojibwe term "Nadouessioux", and can refer to any ethnic group within the Great Sioux Nation or to any of the nation's many language dialects. Before the 17th century, the Santee Dakota (; "Knife" also known as the Eastern Dakota) lived around Lake Superior with territories in present-day northern Minnesota and Wisconsin. They gathered wild rice, hunted woodland animals and used canoes to fish. Wars with the Ojibwe throughout the 1700s pushed the Dakota into southern Minnesota, where the Western Dakota (Yankton, Yanktonai) and Teton (Lakota) were residing. In the 1800s, the D ...

Vegetative Reproduction
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules. Many plants naturally reproduce this way, but it can also be induced artificially. Horticulturists have developed asexual propagation techniques that use vegetative propagules to replicate plants. Success rates and difficulty of propagation vary greatly. Monocotyledons typically lack a vascular cambium, making them more challenging to propagate. Background Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts. Wh ...

Flower Heads
A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomor ...
