Orchids Encircle the Globe
Of all the flowers on earth, orchids are especially fascinating. Not only are they lovely, but they often bring a bit of wonder and mystery with them. Although widespread in distribution, many of them can only be found in isolated, nearly inaccessible places–volcanic mountainsides, misty jungles, boggy swamps, etc.
Beginning quite seriously in the nineteenth century, orchid fanciers have devoted years and whole lifetimes to ferreting out as well as cultivating new varieties of these flowering delights. Although most orchids are obtained these days from nurseries that specialize in cultivating the plants, many of them being produced through hybridization, it is advantageous to understand something of their natural origins.
Orchids are herbacious plants encompassing tens of thousands of known species, with still more being discovered.They show an astouding range of color and shape, which has added greatly to public fascination with them. Gardeners often take pleasure in maintaining a wide variety of orchids to show off their mastery of the art of cultivation.
Orchids grow in practically every part of the earth — the exceptions being the deserts and the polar regions. Some 85% of all orchid species originate in the tropics or subtropics, but this still leaves a large number that come from colder regions. In some parts of the Himalayan region, orchids make up the most abundant family of plants.
By far the greatest number of orchids occur in three large tropical belts:
- Tropical Africa (including islands to the east in the Indian Ocean). These largely belong to the genera (families) Angnecum, Bulbophyllum and Disa. Orchids from here have not been as widely cultivated as ones originating from the other tropical zones, but Africa nevertheless boats many species of interest.
- Tropical Asia. This region, which covers Indonesia and other islands, along with mainland Southeast Asia, is particularly rich in orchid genera. Typical of the region are the large genera Dendrobium, Eria and Bulbophyllum and many smaller ones as well.
- Tropical America. This region includes most of South America, along with Mexico and Central America. Isolated from other parts of the world for eons, this region has an especially large number of endemic genera of orchids, many of which include hundreds of species. Among the large indigenous genera are Epidendrum, Pleurothallis and Oncidium; many smaller genera found here also contribute more than their share to orchids that have found favor among cultivators the world over.
The temperate zones of the southern hemisphere also furnish many orchids, though not nearly so abundantly as do the tropics. In southern Africa the Disa and Calanthe genera furnish a few species judged valuable to cultivation. Australia has a number of genera in common with the tropical Asia. Southern South America boasts a number of temperate orchids, but by the estimation of orchid devotees, they are greatly overshadowed by those
from the vaster tropical-zone part of the continent.
in the norhern hemisphere’s temperate areas, we should take note of the United States, particularly the New England/norhteastern region, as well as Canada. There we find about 20 native genera, whose member species grow mostly in swamps and moist grounds. The most familiar of these are the Cypripediuins or Lady Slippers.
Europe also has many native orchids, but undoubtedly the most famous and showy is the Bee Orchid (Ophrys apifera). The Bee Orchid grows on dry or semi-dry turf, often in open areas within woodlands. Bee Orchids are common near the Mediterranean coast of Europe, and grows (albeit less abundantly) as far north as Germany and the UK.
Orchids vary greatly in how easily they can be grown, although in general they are not the difficult plants that popular wisdom would have it. The most up-to-date guide to today’s orchid care, it is widely acknowedged, is Orchid Care Expert by Nigel Howard, which can be downloaded online. Mr. Howard’s ebook is a full education in itself, suitable for neophytes as well as the more experienced. Also, be sure to visit the Orchid Secrets web site, which has a growing database of postings on many topics of orchid cultivation.
