Interesting facts about orchids


Orchids (Orchidaceae family) are the largest and most diverse of the flowering plant families, with over 800 described genera and 25,000+ species.

There are also over 100,000 hybrids and cultivars produced by horticulturalists, created since the introduction of tropical species to Europe.

Orchids are found on all continents except Antarctica.

The great majority are to be found in the tropics, mostly Asia, South America, and Central America. Some are found above the Arctic Circle, in southern Patagonia, and even on Macquarie Island, close to Antarctica.


Orchids can live on the ground (terrestrial forms), attached to woody plants (epiphytic types) or even thrive under the ground.

A majority of species are epiphytic types. These are anchored on other plants, mostly trees, sometimes shrubs. However, they are not parasites.

Orchids do not have classic root. They have rhizome, tuber or aerial roots.

Size, shape and texture of leaves depend on the habitat. Orchids that live in dry climate have thick leaves covered with wax, while species that live in warm and humid areas have thin, elongated leaves. Certain species of orchids do not have leaves at all.

Some orchids have single flowers, but most have a racemose inflorescence, sometimes with a large number of flowers. Each flower is bilateral symmetric, which means that it can be divided in two equal parts.


All orchids have inferior ovaries which develop into a capsule with (usually six) compartments containing up to millions of microscopic seeds. Only few seeds will develop into mature plant.

The flowers are pollinated by insects, in some cases by birds, and it is common for flowers to have petals modified into perches or guides for their pollinators. Orchids have a dizzying array of pollination syndromes, some fantastically complex.


About a third of orchid species deceive insects into pollinating them. The reproductive parts of many orchid flowers are shaped and colored to look like the kind of insect they hope to attract. Once the insect is interested, the orchid’s pollen sticks to the bug until it flies off to find another orchid that it mistakes for a mate.


Orchid species can differ greatly from one another, with extreme variations in size, weight and color.

Their analysis in the journal Nature, indicates orchids arose some 76 to 84 million years ago, much longer ago than many scientists had estimated.

Many wild orchid species are threatened by people collecting them for sale to orchid fanciers and nurseries. Many are also threatened by the destruction of their habitat by logging and forest clearing.
