Dendrobium orchids are included in a large genus, which has been heavily hybridized. There are two main types of dendrobium hybrids usually available. The Den-Phal (Dendrobium phalaneopsis) type is evergreen, and usually easier to care for. The second type is the Dendrobium nobile type, which is deciduous, and will loose its leaves during its dormant period. Dendrobium hybrids are available in a wide-range of colors, the most common being pinks and purples. There is also a numerous, very diverse range of Dendrobium species as well for the more experienced grower.
