Fragrant Orchids

By:


Fragrant orchids are a pleasure to raise for their sweet perfume and exotic appearance. There are certain species of orchids that are more fragrant than others.

Orchids have evolved into particular shapes, colors and smells to attract pollinators, so they may reproduce. Some orchids attract only a few very specific pollinators, so they have fragrance when these pollinators are the most active, either by day or by night.

Orchid fragrance is an oily substance found in glands called osmopheres on the outside edges of the orchid's roots, leaves and flowers. This oily fragrant substance will change into vapor form, enabling the plant to smell. Not all orchid fragrances can be sensed by humans. These specific fragrances are what primarily attract the insects that pollinate the orchid.

The orchid flower's fragrance is produced at a time daily when the pollinators are the most active, so the fragrance can have maximum effect. For instance, some orchids, namely the Phalenophilus, are fragrant only at night, and are white or other very light colors because they are pollinated by moths.

It is believed that over half of all orchids are pollinated during the day by bees and wasps. The orchid flowers have scents like narcissus, lilly of the valley and sweet peas. The colors of the flowers tend to be bright blue, yellow, purple or green.
