Orchids

Most orchids grow great in a vivarium, and will root to cork bark or driftwood.  Orchidaceae, commonly referred to as the Orchid family, is a morphologically diverse and widespread family of monocots. It is the second largest family of flowering plants, with between 21,950 and 26,049 currently accepted species, in 880 genera.
The largest genera are Bulbophyllum (2,000 species), Epidendrum (1,500 species), Dendrobium (1,400 species) and Pleurothallis (1,000 species).
The family also includes Vanilla (the genus of the vanilla plant), Orchis (type genus) and many commonly cultivated plants like some Phalaenopsis or Cattleya. Since the introduction of tropical species in the 19th century, horticulturists have produced more than 100,000 hybrids and cultivars.
The complex mechanisms which orchids evolve to achieve cross-pollination were investigated by Charles Darwin and described in his 1862 book Fertilisation of Orchids.
