Orchid seeds are so tiny that one flower pod may contain as many as three million. Because they are so small, orchid seeds don’t possess a natural reservoir of food. They rely on a fungus for their development into a mature plant. Once a seed is infected early in its life cycle, it depends on filaments of the mycorrhizal fungus. The fungus supplies nutrition to the germinating seed.
Some orchid blooms have a perfume-like scent, while others smell like rotting meat. One can grow to weigh as much as two tons and another has flowers smaller than a pinhead. Orchids occur in practically all shades except black, from pure white and yellow to mud, with an amazing multitude of stunning combinations between.
Orchids link with passion have deep roots in history. The Greek word orkhis, meaning testicle, was given to this plant, due to its resemblance of the flowers underground tubers, to male anatomy.
It was discovered at the New York Botanical Gardens, through DNA sequences, that orchids belong to Asparagales order of plants that includes asparagus, another acknowledged aphrodisiac. Scientists have had to rethink the evolutionary origins and history of the orchid family.

Orchids have developed highly specialized pollination systems, thus the chances of being pollinated are often scarce, so orchid flowers usually remain receptive for very long periods, rendering non pollinated flowers long-lasting in cultivation. Most orchids deliver pollen in a single mass. Each time pollination succeeds thousands of ovules can be fertilized. Pollinators are often visually attracted by the shape and colors of the labellum.
However some bulbophyllum species attract male fruit flies solely via a floral chemical which simultaneously acts as a floral reward. The slipper orchid Paphiopedilum parishii reproduces by self-fertilization. This occurs when the anther changes from a solid to a liquid state and directly contacts the stigma surface without the aid of any pollinating agent.
Orchids That Produce Pollinia
In orchids that produce pollinia, pollination happens when the pollinator enters into the flower, it touches a viscidium, which promptly sticks to its body, generally on the head or abdomen.
While leaving the flower, it pulls the pollinium out of the anther, as it is connected to the viscidium by the stipe. The caudicle then bends and the pollinium is moved forwards and downwards.
When the pollinator enters another flower of the same species, the pollinium has taken such a position that it will stick to the stigma of the second flower, just below the rostellum, pollinating it.
Northwestern Thailand is a Perfect Habitat For Orchids
The air in the mountains of northwestern Thailand becomes cooler at 1600 meters above sea level. Broad leafed teak forest gives way to conifers and evergreens. It’s a perfect habitat for orchids and one of the few places left where you can see plenty of wild orchid species.
About seventy percent of all orchids are epiphyte, which means they grow on other plants. These particular orchids live on trees, getting nutrients from moisture in the air and water flowing through leaves and along the tree bark. Other orchid epiphytes grow on rocks. There are about 30,000 wild orchid species, as well as another 100,000 man- made hybrids created by experimental cross- pollination. Many beauties outshine their wild parents. Scientists are working to double the number of chromosomes in hybrids to produce larger, more colorful flowers.
5 White Phalaenopsis Orchid in Ceramic Pot.
It makes a perfect gift for birthdays or any special occasion.
It also includes a simple shot cup for easy care.
You need to give your orchid one shot, once a week, with the simple shot cup.
Blooms should last for 8-12 weeks with proper care.
Only needs watering once a week and place the orchids in a room with low to medium sunlight.
It is a beautiful living orchid in a stylish ceramic pot.
Thousands of Plants Have Been Removed Illegally
The demand for the beautiful orchids, are stripping the tropical forests of these plants. Villagers have taken thousands of wild plants illegally from the forests.
Scientists started experimenting with tissue culture on orchids, over fifty years ago. In 1961, a French biologist, managed to separate cells from an orchid shoot. He then immersed the cell bundles in a nutrient solution containing plant hormones. They all multiplied and became identical plants. A million plants of a chosen color can now be produced from a single piece of plant tissue. These plants will be free of disease.
The World Orchid Trade is Worth Millions
The world orchid trade is worth over R273 million. To Thailand’s economy, tissue culture alone is responsible for 196 million in orchid exports from Thailand every year. With both the cut flower and pot plant markets in mind, Asian scientists are working on getting hybrids to last longer and have more color. The cloning process is cheap, since they developed their own technique and try to use natural products, which costs just a few cents a stem, instead of imported chemicals.
