'''''Cymbidium''''' Swartz 1799, is a genus of 52 evergreen species in the orchid family [[Orchidaceae]], subfamily [[Epidendroideae]], tribe [[Cymbidieae]], subtribe [[Cyrtopodiinae]].

It was first described by Olof Swartz in 1799. The name is derived from the Greek word ''kumbos'', meaning 'hole, cavity'. It refers to the form of the base of the lip.

This genus is distributed in tropical and subtropical [[Asia]] (such as North-[[India]], [[China]], [[Japan]], [[Malaysia]], the [[Philippines]], and [[Borneo]]) and North-[[Australia]], usually growing in cooler climates at high elevation.

''Cymbidium'' [[plant]]s are [[sympodial]] and grow to a height of 60 cm and the [[raceme]]s as high as 90 cm. The raceme grows from the base of the most recent [[pseudobulb]]. Each flower can have a diameter of 5 to 10 cm, according to the species. They bloom during the winter, and each plant can have up to fifteen or more [[flower]]s. The fantastic range of colors for this [[genus]] include white, green, yellowish-green, cream, yellow, brown, pink, and red (and there may be markings of other color shades at the same time), with the exception of blue and black. The flowers last about ten weeks. They have a waxy texture. The rounded [[sepal]]s and [[petal]]s have about the same dimensions. They show very diverse color patterns, different for every species.

''Cymbidium''s tend to grow more leaves than most orchids. Roughly eight long, green, narrow [[Leaf|leaves]] originate from the sheath of each [[pseudobulb]].

It is one of the most popular and desirable orchids in the world because of the beautiful flowers. These plants make great [[houseplant]]s, and are also popular in floral arrangements and corsages. They have been cultivated for thousands of years, especially in [[China]]. ''Cymbidium''s became popular in Europe during the [[Victorian era]]. One feature that makes the plant so popular is the fact that it can survive during cold temperatures (as low as 7˚ C or 45˚ F). Orchid hobbyists in temperate climates appreciate the fact that they can bloom in winter, when few other orchids are blooming.

Only a few ''Cymbidium'' [[species]] are commonly grown in nurseries, due to the popularity of [[hybrid]]s. Most are to be found in botanical gardens or in their ever shrinking natural habitat. One of such hybrids was Named "Happy Barry [[Sailor Moon]]" after the popular Anime and manga. It is named due to the fact that its color is identical to the hair color of the title character. <ref>[http://www.soul-hunter.com/sailormoon/myth/happybarrysailormoon.php Happy Barry Sailor Moon] </ref>

== Asian Cymbidium ==
Asian Cymbidiums or Chinese Cymbidiums refer to mainly five species of cymbidiums orchids that are found throughout East Asia in areas of [[China]], [[Korea]], [[Japan]], [[India]], and in parts of [[Thailand]] and [[Vietnam]]. These species are usually grown for their [[variegation|variegated ]]leaves. But plants are also grown for their fragrant flowers and peloric flower structure. Plants are usually grown in long and thin vase like pots. The five species are

	These are among the most decorative of orchids when in bloom, and are attractive all the time owing to the graceful foliage seen on well-grown specimens. There are now many handsome species and varieties and these in their turn have produced, at the hands of the hybridizer, many fine decorative plants, so that a house of cymbidiums produces flowers most of the time, and these last many weeks in full beauty. There are few orchids whose flowers last so long, and the spikes of bloom, often 2 to 3 feet in length, are useful for decorative purposes of all kinds, either on the plants or cut. The recent species, C. insigne, is the most beautiful of all and has already lent itself to hybridization, so that to the very many known hybrids C. insigne will soon add its influence and coloring.—Cultivated cymbidiums are terrestrial, with thick fleshy roots best contained in pots. A portion of tough fibrous loam should be added to the osmundine, about half of each with plenty of broken charcoal to keep the whole porous. The plants will do well for years without disturbance at the roots, but when this is necessary, great care must be taken not to injure them. Division is, in fact, very difficult to accomplish when the pots are full of roots, and it is best practice to pot the plant in a larger receptacle if the roots are healthy, washing out loose earth and removing dead portions of roots first. Cymbidiums may be grown in a temperature of 50° as a minimum in winter, must not be subjected to strong sunlight after March, and never allowed to become dry at the roots, as these are more or less active, even in winter. Being terrestrial, weak manure-water may be applied during active growth. Many species thrive well when planted out in large palm and fern houses among rocks arranged in a natural manner, and when the plants are placed so that the flower-spikes are on a level with the vision, they have a charming effect for many weeks when in bloom, and the environment suite them well. Of the few well-marked species, there are many forms that have been collected and when flowered in cultivation, proved distinct.
