Orchidelirium
Orchidelirium, also called orchidomania or orchid fever, is the name given to the Victorian era of flower madness when collecting and discovering orchids reached extraordinarily high levels. Wealthy orchid fanatics of the 19th century sent explorers and collectors to almost every part of the world in search of new varieties of orchids. Orchidelirium is seen as similar to Dutch tulip mania. Today there still exists some levels of orchid madness, that has some times resulted in theft of exceptional orchids among collectors such as the Ghost Orchid. History 
Cultivation of orchids started in England in the 19th century. Orchids were brought to Europe by companies or individuals who had financed collecting expeditions. Initially orchidelirium was a craze limited to the European upper classes. A difficult plant to grow in cold or even temperate climates, the rich spent a fortune on orchids that died in unsuitable conditions, generally with waterlogged roots in stifling hot greenhouses. Commissioned professional collectors would travel for months all over the world in search of rare new species. It was dangerous work, often romanticised. Many died on these expeditions, from misadventure or conflict with locals, and rival orchid-hunters engaged in willfully destructive behaviours, such as urinating on the plants collected by their rivals after stripping the rest of the habitat bare. These expensive expeditions were often shrouded in secrecy and it was not unusual for collectors to spread misleading information about the locations where new orchids were found. New exotic orchids were most often sold at auction in London, fetching extravagant prices. During this time very little was known about the cultivation of orchids and their survival rate was dismal. Through experimentation and by gathering more information on the growing conditions of orchids in their natural habitat, knowledge was slowly being developed and by 1851 B.S. Williams published the first edition of The Orchid Grower’s Manual (London 1871). Culturally, man-eating plant mythos was developed throughout the nineteenth century around plants foreign to European audiences which were introduced due to importation, like orchids. Examples of Victorian tales with vampiric orchids are H.G. Wells's 1894 short story The Flowering of the Strange Orchid and Fred M. White's 1898 The Purple Terror. Today, international trading of orchids harvested in the wild is now banned by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) adopted in 1973. Still many orchid species are endangered. Orchid smuggling is thought to contribute to the loss of some species of orchid in the wild. See also
