Dendrobium gratiosissimum?

[pheli]

Dendrobium gratiosissimum is a nobile-like dendrobium. It means that a dry winter is needed for the species. Generally, while they stop growing in late autumn, you should decrease the water gradually. In winter, the medium should keep dry as possible.
Besides, summer care should emphasize on lowering night temperature since it is an inland or highland species. The light level for them is as that for most large-flower cymbidiums, especially during winter rest.
