from Malaysia to Indonesia this species is found flowering during February and April. In Thailand this orchid will be found in the South of the country. Here the flwering time is between October and November. Flowers are white with orange yellow lip. they are about 0.5 cm wide and 6 cm to 8cm long, about 5 cm across. Per inflorescence there are 10 and more flowers.
There are several reasons when blooming time in cultivation changes.
- can be the fertilizer or the watering
- can be repotting or re-planting.
- plant's disease from insects or bacteria
- a new environment ( i have reconstructed my nursery, also changing the light conditions from 80% dimming to 70 % )
Too bad, that plants cannot talk. Then we would know. But their language ist "reaction". I have over 50 Bulbophyllum spezies from Thailand + one hybrid and + 1 spezies from Indonesia ( Bulbophyllum graveolens )
