|In 2012 it bloomed from leafless pseudobulbs|

After three years in my collection, Bulbophyllum sumatranum has become a relatively large plant witn many growths. It has bloomed in the past but not as often as I would like. Today I discovered that it has been producing inflorescences but that some of they have been produced by stems that are under a tangle of roots and pseudobulbs. I also found four other inflorescences that are right in the middle of a mess of leaves and pseudobulbs which means they might not have room to expand to their full size. I was delighted by the vigorous growth of this plant and its beautiful flowers, but its tendency to form a tangled mass of growths can be frustrating. I plant to take a piece and attach it to a fern pole to see if grown this way it is easier to tame and it will display its flowers better.
Here are some notes on its culture on my garden
Potting: In a eight inch wire basket.
Media: A layer of medium bark about one inch deep.
Fertilizing: A high nitrogen fertilizer is used when the plant is growing. None is given outside the growing season.
Light: Full morning sun from 8:00 am to 11:00 am light shade the rest of the day.
Watering: The local rain is enough to cover this plant needs outside the rainy season. In the rainy season it rains every day for the whole summer so the plant is constantly wet for months. In the dry season, a whole month can pass with no measurable rain, during this time the plant is thoroughly drenched once a week. If the plant is producing flowers it might get watered every day.
