Thailand is one of few countries that these many orchid species grow. It is estimated that there are more than fourteen hundred species in existence there. The beautiful Vanda coerulea is one of these, with its blue flowers that are reminiscent of its ancestor. To understand orchid species, one first has to understand genera. This is the family, or category an orchid species falls under. There are over eight hundred genera that those twenty-two thousand orchid species fall under. Species can best be explained as a separate biological class.

Regardless, the number of orchid species nearly equals the number of bony fishes and is more than twice the number of bird species, and about four times the number of mammal species. The family also encompasses about 6–11% of all seed plants.

The mitigation is that the orchid world is so diverse — some 30,000 species and even more human-bred hybrids — that different and unusual orchids are never far away. Even within the realm of the moth orchid, you will find novel varieties bred by and for connoisseurs. (On Sunday, the National Capital Orchid Society hosts an auction at Behnke Nurseries in Beltsville, starting at 10 a.m.) More to the point, some of the mass-market, commodity moth orchids are devastatingly beautiful.

It is said that there are twenty-two thousand or more accepted orchid species in existence. That is a difficult number to imagine even for the most fertile imagination. The numbers vary among the experts whom you speak to about the subject. There are about eight hundred new orchid species added per year.

Asking me what types of orchids there are is like asking me what types of people there are. Well, there are tall and short people, smart people and not-so-smart people, introverts and extroverts, people with different skin colors, and people from different parts of the world.

The Orchidaceae are a diverse and widespread family of flowering plants, with blooms that are often colourful and often fragrant, commonly known as the orchid family. Along with the Asteraceae, they are one of the two largest families of flowering plants.

Dendrobium is actually one of the largest orchid genera. Dendrobium species live as epiphytes and lithophytes in New Guinea, Southern China, Thailand, Japan, Australia, New Zealand, Tahiti and more. As a result, it’s hard to generalize how to care for these types of orchids. Some of them require cool nights of 50 to 59°F (10 to 15°C) while some of them require warm temperatures in the 80s°F (27°C). That’s why it’s so important to understand their natural environment so that you can make them happy.

The answer, happily, is yes. This might be as miraculous as the flower itself, given that the propagation technology of tissue culture has created the moth orchid conveyor belt. With a flowering plant from scratch in as little as three years, growers produce so many varieties that they don’t even bother to name them.
