I got this plant in bloom two years ago. I have a weakness for these large, long lasting Bulbophyllum species. It is doing well in my hot, wet greenhouse. So well that I needed to re-pot after dividing it a year ago.
Bulbophyllum echinolabium grows in Borneo. It is warm to hot growing and likes high humidity and frequent watering. It is unpleasantly fragrant and blooms in spring and summer.
This plant is in sphagnum over peanuts in a 6-inch plastic pot. There are three pseudobulbs and a new growth. The plant stands 12 inches above the pot. I went from a 3 1/2-inch pot all the way to a 6-inch pot. The roots were quite good and the big pseudobulbs need an inch and a half for each generation.
