Coelogyne assamica Linden & Rchb. f. 1857, the flowers look different from what is identified in other places as assamica. But that is what the label said.

I brought this plant in the Puerto Rico orchid society show last spring.  I wanted to see if it would grow and bloom in my area.  Green flowered Coelogyne thrive and bloom well in my location and will even endure relative neglect with little complain.  This species is a refreshing change from the green flowers of my other Coelogyne.  I have tried to grow white flowered Coelogyne with little success.  I tried mooreana and it died.  I also tried lactea, this one grew well but flowered so rarely I gave it away.  Perhaps in the case of lactea, I was growing it wrong.
