Three Most Common Orchid Types

Getting to know the types of orchids you want to grow and learning how to care for them will get you off to a good start. There are three most common orchid types, with each types grows under different environment and has different care requirement. Take the time to familiarize yourself with the different types of orchids below.

Types of Orchids

Orchids can be grouped into three basic types – terrestrial, epiphyte and lithophyte.

• Terrestrial orchids are ones that grow in or on the ground.

• Epiphyte orchids grow on other plants or trees – although they’re not parasitic. People often refer to this type of plant as an air plant because its roots are in the air rather than soil.

• Lithophyte varieties are those that grow naturally on solid rock.

Terrestrials grow beneath usually light soils or other ground level material in their natural environment. Many varieties have pseudobulbs that store water and nutrients. Cymbidiums are an example of a terrestrial orchid.

Epiphyte varieties obtain water from the air and feed off the debris that collects around them or on the plant they’re growing on. Their roots are accustomed to being in the air so potting this type of plant in dirt is likely to suffocate it. Many Dendrobiums are epiphyte orchids.

Lithophytes are a little like epiphyte types in that their roots are often exposed to the air and they obtain nutrients from debris. Some Dendrobium orchid varieties grow on rocks.

Growth Types

Orchids can be further separated into two groups according to how they grow.

• Monopodial orchids have a root and growth system that expands vertically. They often have long stems. The Phalaenopsis falls into this category.

• Sympodial orchids extend in a horizontal manner, with growth moving along the root system. They can develop multiple stems. Dendrobiums and Cattleya orchids fall into this category.

The requirements of different varieties or orchids can vary quite a bit. Most orchids dislike being water-logged so they need to have good drainage. Many like their pot to be almost dry before they take in more water and some like to maintain a “just damp” condition.

The amount of light they prefer also varies from one variety to another but fortunately, there are usually visible indications that your plant is getting the wrong amount of light. An orchid’s leaves should be a bright green color, rather than the deep green of many shade loving plants. Deep green leaves often suggest too little sun. Conversely, when your orchid is getting too much sun, the leaves may burn or begin to display reddish spots or orange scorch marks on the leaf tips.

If you’re the proud new owner of an orchid, gather some information the particular requirements of that orchid type and you’ll be well on your way to successfully growing your own orchids.
