It is the adaptability of the orchids, which is the cause of their spread throughout the world. Orchids use resources such as insects and birds of the region, to ensure pollination and reproduction.
Each type of orchid is dependent on a particular pollinating agent. The orchids use variety of tricks to insure pollination. Some of them attract pollinating agents with the help of fragrance or scent of food.
While the others manage to fool the male insects, by imitating the ‘female insect look’ or appearance. Because of this, future of the orchids growing in the wild, depends heavily on conservation of the entire ecosystem.
Extinction of a species of insect or bird, may mean extinction of the orchid depending on it. The following are some interesting facts about orchids:
- The orchids have a unique identification signature, in the form of a structure, which harbors its male and female reproductive organs. This structure is referred to as ‘column’.
- Orchid flowers are famous for their colors and one can find every imaginable color and shade in orchids.
- Some of the orchids have sweet fragrance, while few others, smell like stinking or rotting meat.
- Orchid flowers come in varying sizes. The flowers of Platystele stenostachya are small enough to fit on the head of a nail. On the other hand, those of Cattleya gigas orchid are eight to eleven inches across.
- The giant in the orchid family is Renanthera storei. It can grow to a height of 20 feet.
- An orchid can live as long as 100 years, whilst the orchid flowers can last for few weeks. However, the blossoms wilt quickly, after fertilization.
- There are very few species of the orchid family that can be used as food or to obtain medicine from it. In China, some of the orchid types are used as aphrodisiacs.
- In tropics, different types of orchids are found in the cloud forests in mountainous regions, while they are less in numbers, at lower elevations, in the rain forests.
- Orchids from the temperate areas, like Indiana, grow on the ground. On the other hand, orchids in the tropics, grow on trees or rocks.
- The orchids are not parasites; but use decaying organic matter collected on the bark of trees or in fissures of rocks for their nourishment.
- In the past, the roots of the orchids found in Europe, were used as aphrodisiacs.

Orchids are loved for their colors, sizes, shapes and are maintained as potted houseplants in flower gardens or greenhouses.
In spite of the many varieties of orchids, these delicate, exotic plants, the world over, are being threatened with extinction. Though, 42 different orchid types are found in Indiana, many of them are endangered for one or the other reason.
There are at least 20,000 to 30,000 species of orchids that are found in the wild. Added to these are, approximately, 10,000 orchid types. that are created by man, since 1856.
All of these orchids come under the family Orchidaceae, which is considered as the largest family of flowering plants. After the grasses, the Orchidaceae, is the second-most widely distributed plant family on the Earth.
The orchids have infiltrated every ecosystem and habitat, except the aquatic, on the Earth. Even the Arctic Circle, which is infamous for its sub-zero temperatures and adverse living conditions for man and the animals, have three types of orchids.
Orchids are found on every continent, except the Antarctica. Two of them, in Australia, have found shelter under the ground and their flowers can be seen above the ground for brief spell of time.
From a botanist’s point of view, there are only two orchid types: Terrestrial orchids and Epiphytes. The distinction between these orchid types is as follows. The orchids varieties or the species that grow on the ground come under the terrestrial orchid types.
On the other hand, orchid species that grow on trees or rocks, come under epiphytic orchid types. Let’s take a look at some of these types of orchids.
- Anota violacea
This orchid’s name signifies the absence of “ears” on the floral column. This orchid, a terrestrial orchid, is sometimes also referred to as Rhynchostylis violacea orchid.
These orchids are native of the Philippines. The flowers of this orchid are small in size and bloom in winter and spring, donning lavender and white colors. This orchid proliferates in warm temperatures, shady light and moisture.
- Anguloa uniflora
This orchid is named after Don Francisco de Angulo. It is also known as ‘boat orchid’ or ‘tulip orchid’. This terrestrial orchid is 18 to 24 inches tall and is native of the Colombian Andes.
The large fragrant flowers are creamy-white in color. One of petal, ‘lip’, of the flower is hinged. When insects enter the flower to remove nectar, the lip pushes it against the column to facilitate the pollination. These orchids bloom in spring and summer and love shade and medium to cold temperatures. Watering should be decreased after it has matured, to facilitate flowering.
- Ascocentrum curvifolium
The name of this orchid is a reference to its spurred lip. This orchid, an epiphytic orchid, is a six-inch tall, monopodial plant, that is native of Thailand.
The flowers of this orchid are half-inch in size and orange-red in color. This orchid’s bloom time, which favors medium to warm temperatures, shady light, and even moisture, is late spring and summer.
- Cattleya
This is the most popular orchid, having more than sixty species. The orchid is named after William Cattley, an orchid collector. This orchid type is native to the American tropics and is found from Mexico to Brazil. These epiphytic orchids which bloom in many small, narrow flowers are brightly colored and have narrow pseudobulbs and leathery leaves.
These orchids love medium to warm temperatures and bright but not harsh light. This orchid type also prefer air circulation, high humidity and effective drainage of water. When it comes to orchid gardening, the Cattleya orchids are preferred.
