hahaha...perhaps that "Belimbing" is the same as our "Balimbing" or the star fruit? I never knew orchids liked that tree. My grandma has a number of those trees but somehow all of her orchids were on the chico tree (Manilkara zapota). But they were all Philippine species orchids which were abundant during her time. Perhaps they loved the oppressive shade of the chico. She wouldn't attach too many orchids on her mango tree either. Many think that the mango wood is "sour" or maybe they mean acidic, and they say orchids don't like it either. But my grandma's Dend anosmum thrived on her mango tree for many years.
