Orchids are the most unique type of houseplants.
Unlike any other plant, there is a certain growing condition for them to survive.
Orchids are classified according to the light and temperature they need.
If orchids are grouped based on their need for light accommodation, they are classified as high, medium, and low.
To test for the right amount of light an orchid needs, you can place your hand 6 inches above the leaves and stare at the shadow that is cast.
If a sharp-edged shadow appears, then there is high light.
A soft-edged shadow means there is medium to low light.
Orchids can also be classified as warm growing, intermediate, and cool growing if temperature is considered.
Cool growers, basically, prefer the temperature during winter nights which is less than 50 degrees Fahrenheit.
Warm growers, on the other hand, do not like the temperature below 60 degrees Fahrenheit at night.
Intermediate kinds can be comfortable on temperatures between the two.
The most common kinds of orchids are Phalaenopsis, Cymbidiums, Cattleya, and Dendrobiums.
Phalaenopsis grows well with low light strength and chooses warm temperatures.
This kind of orchid has a tall flower stalk that comes out from the smooth, shiny leaves, and produces several flat pink or white flowers.
Cymbidiums require high light intensity, but cold temperatures in order to bloom beautifully.
They have lush foliage and tall, arching strands of flowers in submissive colors.
Medium to high light intensity and moderate temperature are preferred by the Cattleya kind of orchid.
Its flowers range from different sizes and colors, which are mostly sweet-smelling.
Dendrobiums vary in size and on how the flowers are produced.
There are flowers which are erect, arching, and some grow in clusters.
Those are the classifications and kinds of orchids.
If you decide to grow an orchid in your home, you may choose any of those and just remember their preferred growing conditions.
