There are so many diversified and exquisite flowers on Earth.

Orchids are a family of flowering plants and prominent among the largest flower families of the world.
They are perennial plants.
In the flower kingdom, Orchids are of exquisite beauty.
Attractive color, scent and shape are prominent characteristics of orchids.

Except black, Orchids come in almost all colors.
Compared to other flowers, Orchids are quite different in structure, shape, size, and characteristic.
Except in coldest regions, Orchids are found almost everywhere in the world.
Mainly, Orchids flourish in tropical humid regions.
Orchid plants usually have stem, leaves and flowers, and branches grow from stem.
Orchids don’t have woody stem.
Depending on habitat and species, their structure, size, and leaf composition can vary.
Orchid leaves are thick and heavy.
Some orchid’s leaves last for several years.
But some species’ leaves fall off after one year.
Various orchid species grow in different places of Bangladesh, including the Evergreen forest, Sal forest, and Mangrove forest.
Orchids grow well in Chattogram Hill Tracts, Sylhet and forests of Mymensingh.
2 types of orchids are available in our country.
Among these, some orchid species survive depending on other plants.
They grow on the trees.
They have long, strong and thick roots, and sustain by getting necessary nutrients from host tree.
But they don’t harm the host tree.
Usually, these orchids are found on old tall trees of the forest.
And, some other orchid species grow on the ground.
They have cluster of thin roots and live independently taking nutrients from the soil.
Almost all orchid species need moist weather to survive.
They cannot withstand direct sunlight and heat.
So, they grow in somewhat shady places.
Usually, orchids first flower at the age of 3-5 years.
The flowers bloom from January to July.

Here, native orchids as well as foreign species are being cultivated.
In addition, many hybrids orchid species are being produced.
At present, orchid farming has become a great source of income.
But, decreasing forestlands and trees have resulted in decline of orchid species diversity.
As a result, with declining orchid dependent organisms, natural balance of the environment is getting damaged.
So, with proper research and conservation management, we have to conserve the still sustaining orchid species of Bangladesh.
Only then the orchid dependent organisms will survive, and our environment will flourish.
