The Slipper Orchids

The slipper orchids are not likely to be confused with any others; with the exception of a single species, all the members of the subfamily Cypripedioideae have the lip or labellum modified into a pouch, an inflated bag-shaped organ.

The Cymbidiums Orchids

Easy culture and a lavish show of long-lasting flowers have made cymbidiums favorites with gardeners and commercial cut-flower growers alike.

The Dendrobium Orchids

The dendrobium tribe includes only four genera, three of which are not widely grown.

Light For Orchids

Light is another critical factor in growing and inducing orchid plants to bloom. In fact, lack of adequate light is the chief reason for an orchid's failure to bloom. On the other hand, too much of a good thing is a problem, as well - for instance, when it results in sunburn. And although some … Continue reading Light For Orchids

Watering And Feeding Orchids

Orchids are supposed to do best if the water is slightly on the acidic side, with a pH of about 6.5. However, they have been grown successfully in alkaline water with a pH of 7.5. Most municipal water supplies will present no problems, but there are exceptions. Water high in calcium and magnesium salts can … Continue reading Watering And Feeding Orchids

These and other orchids from time to time have been considered useful in medicine, but the only orchid of true economic value is Vanilla planifolia, the source of vanilla flavoring. This orchid … Continue reading History Of Orchids
