Yes it is a very slow growing species and requires atleast 3-4 fans before it can bloom. It grows in a specific locality in Kerala (my neighboring state) and is listed as endangered. It grows along side grasses on a mountainous terrain and gets bright light during normal growing stage and gets higher light during winter.
In its natural habitat, It is rainy season from end of May till end of October during which it is hot and humid and winters are cool (~10 Degrees Celsius)
Do share a picture of the plant.
