What are bidens?

bidens is a family of flower in the family Daisy, Asteraceae. It has about 200 species covering a wide geographical range, with common names including beggar, burr-maarigolds, Stickseeds and sunflower. These names refer to the method of plant scattering, burrs that stick to clothes or fur, allowing them to transmit over long distances. It is assumed that the burrs resemble ticks and could be transmitted over long distances on the beggar's clothes. Plants bidens growing in limited areas, especially plants on the islands, often have reduced burns and have developed features that promote seed scattering. Plants resemble daisies with bright yellow or white flowers. bidens are usually grown in containers, often as a filling plant. It is important to maintain the soil well moistened aoplodn and immediately cut off dead flowers to support abundant flowers. Plants tolerate heat slightly and prefer full sunlight. b. Pilosa or Spanish needle and b. Tripartita or three-alcoholic beggars are sometimes used as food, with shoots and leaves cooked and consumed as vegetables. b. pilosa is also used as a honey plant, along with b. Cerna or Burr-Marigold.

in Hawaii are bidens call koko'olau and sometimes used as tea. Many species have a very limited range and are endangered by extinction. It belongs to b. Amplectens or wai'anae koko'olau, found only on the island of Oah and b. Other endangered types of Hawaii are b. All these species are threatened by the loss of the habitat, especially caused by brushes and invasive weeds.

some others bidens species with very limited ranges are b. Mannii , endemic to Cameroon and b. Simpicifolia , endemic for Ecuador. Some types of bidens , on the other hand, have become invasive when they were introduced into a new environment. b. Frondosa , commonly called devilish beggars or weeds pitchfork, is classified as an invasive extraterrestrial plant of European and Mediterranean protection of plants (EPPO) and as an environmental weed in New Zealand.
