Orchid Types
There are many different species and hybrids of orchids, however there are actually only two different types of orchids. The first orchid type is the epiphytes orchids which grow on poles or in rocks and trees. And the second orchid type is the terrestrial orchids which are species that grow on the ground.
The most popular orchid types are the terrestrial orchids. Orchids that have roots that grow beneath the surface of the soil like most other plants are called terrestrial orchids. Some orchid types are also semi-terrestrial, meaning that they have both aerial and underground root systems. A terrestrial orchid that has 40 natural found species and thousands of hybrids is called Cymbidium orchids. The Cymbidium was one of the first species of orchids that were cultivated. Cymbidium orchids are an example of a terrestrial orchid that grows on the ground and can also grow on trees and rocks. They can grow very well in decayed leaves, loose humus, or rotted wood. The natural habitat of the Cymbidium orchid can be found from Japan to Southeast Asia. They are also found in Australia. So popular because they are easy to grow Cymbidium orchids are a perfect choice for the beginner. They will provide beautiful flowers every year with the proper care.
The term epiphyte refers to any plant that has a root system above the ground. This term is not reserved to a type of orchid. The best known epiphyte orchids are the Dendrobiums. Dendrobiums are easy to grow, but require more care than Cymbidiums. They also do not flower as easily or on a regular basis. There are over 1000 species of Dendrobiums. They are found in Australia, Polynesia, Northern India, and South East Asia in naturally tropical conditions. Because of their natural environment Dendrobiums should be kept in humid growing conditions that are warm and moist for them to thrive. Also popular in the epiphyte type of orchid is the Phalaenopsis. These orchids have long lasting blooms and are easy to grow. They can be found in various colors including pinks, yellows and stripes, and are often used in weddings.
Epiphytic orchids grow on structures like trees, rocks, and poles. However, they do not receive nourishment from their host. Instead they establish a fleshy root system on branches of bark and in cracks of rocks where organic matter accumulates and the roots absorb the nutrients for the plant. Through both dry and wet cycles the epiphytic orchids roots can sustain the plant. The roots have a tough stringy core surrounded by a spongy covering that is off white that can easily absorb water. During rainy periods this outside cover soaks up water. After it is completely full of water the cover of the root turns a light green color. The root system will then gradually release water to the plant tissues of the orchid. Suspended from rocks or trees, epiphytes thrive in open airy conditions with filtered light.
