Hot Climate

Orchids suitable to cultivation in a hot climate are those which are able to tolerate temperatures of 35°C or more during summer days. Some examples are Aerides, Angraecum, Ascocenda, some Cattleyas species and hybrids, Dendrobium (phalaenopsis or biggibum), Miltonia flavescens and spectabilis, Oncidium baueri, cebolleta, flexuosum, jonesianum, morenoi, pumilum or sarcodes, Phalaenopsis (species and hybrids) and Rhynchostylis.

Some of these orchids, however, like Vanda (except coerulea), Phalaenopsis and Dendrobium phalaenopsis and bigibbum, will not tolerate temperatures less than 15°C.

Cool Climate

Some orchids that can be cultivated in places where the temperature generally is between 0°C and 20°C and rarely reaches 25°C during the summer are Anguloa, Cymbidium, Dracula, Dryadella, Lycaste, Masdevallia, Miltoniopsis, Odontoglossum, Paphiopedilum in general, some species of Encyclia, Oncidium, Coelogyne and Dendobrium.

In spite of this list, many orchids which are supposed to bloom only in an intermediate or cool climate or greenhouse, may also bloom in hotter or cooler conditions.
