Genus of forty species of epiphytic and terrestrial orchids, originating in central and southern Asia and Australia; there are many hybrids on the market, with flowers with showy colors. They produce numerous flattened pseudobulbs, linked together by short fleshy rhizomes; each year the plants produce new pseudobulbs, each of them bears a dozen long rigid, ribbon-like, slightly arched, bright green leaves, which can reach 90-100 cm in length. In spring, at the base of the pseudobulbs, a long erect, fleshy stem develops, which bears up to 15-20 large fleshy, white, yellow or pinkish flowers. There are many hybrids on the market, even with small or very large flowers. The flower is generally pale, pastel in color, and has a conspicuously speckled labellum; they remain in bloom for weeks, for this reason they are among the most widespread orchids as cut flowers.
The most common Cymbidium on the market are of Asian origin, and come from the mountainous areas of Central Asia; therefore they love places not too hot, with summer temperatures below 30 ° C, and cool winters; they do not fear short frosts, even if during the winter they are usually grown in apartment or in a cold greenhouse.
To encourage flowering, it is good to grow the plants outdoors, in a cool place, until the first cold winters arrive, so we bring the cimbidio plant at home or place it in a place sheltered from frost. Remember to grow in a position that is not excessively sunny, but well-lit and well-ventilated.
The ideal temperature for growing cymbidium orchids is around 18 ° C.
It is good, when grown indoors, to place cimbidium plants in well-ventilated areas with a good degree of humidity.
It is essential to guarantee these orchids a high degree of brightness, so much so that in low light environments, especially in winter, it is necessary to resort to artificial lighting to ensure the right degree of light for orchids.
