We have seen Cymbidium aliofolium growing abundantly in seasonally dry hot forest in Sikkim, Arunachal Pradesh and Laos where it is the most common epiphyte in lowland forests. The photo below shows Zoe and Zoe on our 2013 expedition to Sikkim by a a good sized Cymbidium aliofolium close to the Gangtok Road.
The natural habitat is warm and has a distinct dry season which Cymbidium aliofolium is addapted for with its very thick leaves. The species flowers on and off throughout the year and usually produces a number of spikes in early Autumn.
We find these warm growing Cymbidiums respond well to growing in baskets hung high in our Warm Asia section where they grow hot and bright but we take care to keep them really wet during the summer (monsoon season in the natural habitat). Cymbidium aliofolium in Sikkim below.
