I don't mean to burst anyone's bubble, but I have to differ in my opinion on the ease of cultivation for this species of Bulbophyllum.
I have a colony that's been around for 2 - 3 yrs. I can safely say in my experience this is not an easy Bulbo to grow and therefore not a beginner's Bulbo by any stretch of the means.
It does have a leaf that only develops and appears on new growths, and it does fall off on the onset of dormancy (mid-fall).
It requires a much drier dormancy.
Older pseudobulbs only live up to be about 2 - 3 yrs old.
They grow extremely slow. Only putting out at most 2 new growths per new mature pseudobulb. New pseudobulbs mature in size in one full growing season.
Root growth for this species is rather sparse and only 5 or less roots will be produced per pseudobulb.
I've found pseudobulbs of any age to be particularly susceptible to rot if they are grown too wet. During dormancy, diminishing the amount of water it receives is crucial or it will start the onset of rot. I've also found that it is particularly prone to root rot if grown too wet. In essence, there is still a limit to the amount of moisture this plant can safely absorb during the growing season.
High humidity is a definite plus and greatly aids in the proper maintenance of this plant.
If not grown correctly, it has a tendency to peter out.
