Orchid Types

Although there are many, many different species and hybrids of orchids, there are actually only two different types of orchids.One type of orchid is the terrestrial orchids which are species that grow on the ground.The other type of orchid is the epiphytes orchids which grow in trees, rocks or on poles.

Terrestrial orchid species are some of the most popular orchids.Although terrestrial orchids have roots that grow beneath the surface of the soil just like most other kinds of plants, some terrestrial orchids are semi-terrestrial.This means that they have both underground and aerial roots.Cymbidium orchids are a terrestrial orchid that has 40 species and thousands of hybrids.They were one of the first species of orchids to have been cultivated.These orchids are a great example of terrestrials that not only grow on the ground but, they can also grow on trees and rocks.They grow extremely well in the loose humus of rotted wood or decayed leaves.Cymbidium orchids can be found in their natural habitat which extends from Southeast Asia to Japan and they can also be found in Australia.Cymbidium orchids are so popular because they are easy to grow and are therefore a perfect choice for beginners.Plus, with the proper care, they will provide beautiful flowers every year.

The term epiphytes are actually not reserved to a type of orchid.It refers to any plant that has a root system above ground.Dendrobiums are the best known epiphytes orchid.Even though they grow more compared to terrestrial Cymbidiums, they require more attention and grow flowers less regularly.There are over 1000 species of them.The natural habitat of this variety are in Northern India, South East Asia, Polynesia, and Australia.Dendobriums require to be kept moist for it to continue growing, as its natural habitat is in humid areas in the tropics.Another popular epiphyte type of orchid is the Phalaenopsis. This variety produces long-blooming flowers and are very manageable to take care of.They are often seen at weddings and can be found in various colors including pinks, yellows, and even stripes.

Epiphytic orchids grow upon structures like trees.Although they grow upon the tree, they do not receive its nourishment from the tree.Through embedding their spongy roots on tree bark or branches, they manage to cling to the surface of the tree.The organic matter that accumulates between the roots and branches is used as nutrients for the plant.  The roots of epiphytic orchids can also sustain the plant through wet and dry periods.The off-white, spongy covering of the tough roots can easily absorb water.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.Some epiphytic orchids are known to thrive on rocks.As they are suspended from trees or rocks, the epiphytes thrive in filtered light and always in open, airy situations.
