Cymbidiella rhodochilla
 

Hi !! I have just bought a Cymbidiella rhodochilla bareroot . Does anybody knows hot to grow it . Is it terrestrial ? Please help me !!

I dug up an old issue of Orchids Magazine, November 2005.
All three species of Cymbidiella were discussed in the article, Orchids of Madagascar. Here is the info provided.

Grows in the Eastern Rainforest of Madagascar.

Rainfall amounts over 80 inches topping 240 inches in some parts. No dry season.

Temperatures are high, with mean winter temps in the coolest season ranging from 64F to 50F.

Cymbidiella pardilina (syn. rhodochila) lives in association with a staghorn fern, Platycerium madagascariense. It is thought that this association is very important to the orchid, at least in nature. The roots of the orchid grow into the crown of the fronds of the fern that form a protective shell against direct sunlight and dessication. Ants are also often found residing in the crown of the fern. the orchid and fern live epiphytically up to 65 feet high on tree trunks.

Thats all it gives regarding 'culture'. As with other orchids known to have associations with ant colonies, this could mean acidic conditions at the roots.

Cymbidiella flabellata is the terrestrial species, found in the boggy areas.

Cymbidiella falcigera grows on Raphia palms in the marshy ground, listed as difficult to establish in cultivation.

Good luck.
