Orchidaceae have about six hundred and fifty genera and over twenty thousand species of orchids. Only in our country can we find over eighty thousand species of orchids that grow both in marine and mountain places. To these we must add the non-spontaneous ones, that is, the crossed ones that become rare from a botanical point of view. Orchids are classified according to specific criteria such as the characteristics of the flowers and leaves, the environment in which they live and more generally the traits that are part of the plant as a whole. On a biological level, orchids are divided into "poor", "terrestrial", "parasitic", "semi epiphyte" and "epiphyte". The characteristic of epiphytes is that of having root areas that use trees as support. The peculiarity of the epiphytic seeds is that of surviving on the branches and on the rock. The poor ones live well rooted to the ground with root areas. The terrestrials, as the name also says, are born in the ground and have their roots well inserted in the ground. The parasitic orchids instead feed on the organic nourishment that they can find in the place around them and therefore do not use chlorophyll as an energy element. Among the rarest orchids we can find those of African origin, those of the genus Angraecum, which in turn is divided into over two hundred subspecies. To these is added the genus Miltonia which has Brazilian origins and whose flowers can measure up to eight centimeters. Among the most important and particular are the species of the genus Odontoglossum and the so-called "tigers" of the genus Riossoglossum. Finally we mention the genus Laelia and that of American origin Lycaste.
The rare species today are protected and therefore it is very difficult for anyone who tried to grow them in an environment other than their own. In addition to the fact that cultivating rare species would therefore be a crime, precisely because rare and therefore particular, these species are unable to live and adapt simply to a habitat other than that of origin. There are in fact many precautions that must be taken in order for them rare orchids can grow and develop in all their beauty. In particular, diversified methods are needed for each of the species that have been previously created. Each type of action to be taken must tend to recreate the environment from which it is performed rare orchids they come, in which they grow spontaneously and without the need for human intervention.
For example the Angraecum type, needs a lot of brightness and a temperature that is not excessively hot.
