The Two Types Of Orchids

Here is one fact that you should know about orchids......There are only two types

of orchids! Although we see several different hybrids and species of this flower, this is 100% true. Orchids are categorically defined in places where they grow. Orchids that grow on the ground are called "terrestrial orchids" whilst "epiphytes orchids" grow on rocks, poles and in trees.

Most of the more popular orchids come from the terrestrial species group. These orchids have roots that can grow beneath surface soil like most plants, however they can also be semi-terrestrial which means these orchids may have aerial and underground roots. One example of a terrestrial orchid is the cymbidium orchid, which have around 40 different species and thousands of hybrids. Cymbidium orchids are one of the first orchid species to be cultivated by man. These orchids are classic examples of flora species that can grow in the ground, on trees and on rocks. They grow and survive well in the loose humus of decayed leaves and rotting wood. They can usually be found in their natural habitat from countries in Southeast Asia and Japan, to the wilderness of Australia. Cymbidium orchids are perfect for new gardeners since they are easy to grow and easier to maintain. They also give off beautiful flowers every year.

Epiphytes refer to any plants or flowers whose root systems are above ground. They are not exclusive to orchids only. The best example of epiphytes orchids are dendrobiums. Dendrobium orchids grow quite as easily as Cymbidiums but they require more maintenance and grow fewer flowers. This type of orchids has more than a thousand species. Dendrobiums are tropical flowers that grow best in warm, moist and humid climates. Phalaenopsis is another type of epiphytes orchid that has gained popularity. They are a hardy plant that is very easy to grow, with flowers that can stand a longer period of time than other flowers before wilting. Phalaenopsis are usually used as floral arrangements during weddings because of their very attractive colors like pink and yellow. You can even have striped Phalaenopsis!

Epiphyte orchids usually grow on structures like trees though they do not get their nourishment from the tree. Organic matters accumulated by the roots and branches of the trees serve as nutrients for the plant. Epiphyte orchids have meaty roots attached to the barks and branches of the tree which serve as a storage room for their nourishment that will sustain the plant through long periods of wet and dry spells. Their roots have a spongy white layer that can absorb water and any other liquids within its vicinity. This is especially helpful during the rainy season when it can absorb the water from the rain. Their color will change to light green when the covering has been deeply saturated. As long as the roots of the orchid have moisture and water, they can evenly distribute these necessary fluids to the plant tissues. Other species of epiphytic orchids can be found clinging to rocks also. This type of orchid grows and thrives in filtered natural lights and lasts longer in open and airy environments.
