Heat Tolerant Cymbidium Orchid Culture

Posted by Team Orchid-Tree on

Heat-tolerant cymbidiums (HTC) are cymbidiums that will grow and bloom in a tropical climate where there is no drastic drop in day & night temperatures. In contrast, the standard cymbidiums require the night temperature to drop to below 8 degrees in winter to initiate blooms. These cymbidium hybrids are the result of hybridizing the tropical cymbidium species like C. ensifolium, C. aloifolium, C. canaliculatum etc. with the cold-growing species.
