Phalaenopsis tetraspis var. imperatrix 'blue-grey' X 'grey' 
Blooming size plants in 2.5" pots available for sale at $30 each. 
Only 10 plants available. 
The plants are from a sibling cross between 2 rare and dark colour forms of tetraspis. The plants are the last batch of seedlings from the seedpod, earlier batches of seedlings have already flowered. The flower samples are from plants of the exact same batch.  Flowers from this batch have many variations, from dark brown to dark grey. These dark colour forms are quite rare and difficult to come by. Flowers from this batch will be either brown or grey, both being uncommon colour forms of tetraspis. The plants are productive and the inflorescences are able to branch.
