How Many Orchid Types Are There?
Although there are many, many different species and hybrids of orchids, there are actually only two different orchid types. One type of orchid is the terrestrial orchids which are species that grow on the ground. And the other orchid type is the epiphytes orchids which grow in trees or rocks.
The most well liked orchids usually belong to the terrestrial orchid type. But some of the terrestrial orchids are only semi-terrestrial, although this orchid type typically has roots which grow underground like the majority of other plants. This term means that the roots of these plants are found both under and above the soil.
There are as many as 40 species and thousands of hybrids that make up the terrestrial orchid type known as Cymbidium orchids. This species was one of the original ones to be grown by man. These orchids exemplify terrestrials that can grow not only on trees and rocks, but also on the ground. Rotted wood, decayed leaves and loose humus are excellent growing media for these orchids.
With a natural habitat that reaches from Southeast Asia to Japan, cymbidium orchids also appear in Australia. Beginners particularly love cymbidium orchids because they are quite easy to grow. When appropriately cared for, the plants will bloom wonderfully each year.
The term epiphytes is actually not reserved only for orchids. It refers to any plant that has a root system above ground. Dendrobiums are the best known epiphytes orchid types. Although they are easy to grow, they require slightly more care than Cymbidiums and do not flower as easily on a regular basis.
This orchid has over 1000 different variations. They are native to Polynesia, Northern India, South East Asia, and Australia. Dendrobium orchids prefer a moist and warm environment similar to their native habitat, so it is important not to let the soil get too dry
Another popular epiphyte is the Phalaenopsis orchids. These orchids are easy to grow and have long-lasting flowers. They are often seen at weddings and can be found in various colors including pink, yellow, and even with stripes.
Trees are a common growing spot for epiphytic orchids. This type of orchid does not use the tree for sustenance even though it grows there. By attaching their thick roots to tree branches or bark they are able to maintain themselves. The plant is able to nourish itself by using the buildup of organic matter that collects in spaces found between branches and roots.
The roots of epiphytic orchids can also sustain the plant through wet and dry periods. The tough, stringy core of the root is surrounded by a spongy off-white covering that can absorb water easily. When it rains, this cover soaks up water. When it is completely saturated, it turns light green. The orchid’s roots retain the moisture and will release it gradually to the plant tissues.
Other epiphytic orchid species use rocks as their preferred place to grow. The best growing conditions for epiphytes, whether they hang from trees or clings to rocks, are those that include open areas with filtered light and lots of circulating air.
Now you know a fact that very few people know, that there are thousands of orchid species but only two orchid types.
