Bulbophyllum species- one of the most diverse and fascinating species (in my opinion). Usually after a few days of rain follows by sunny days, these pretty orchids tend to blossom. To some people, they don't look like the typical orchids; but to me, I am crazy over them.

Bulbophyllum vaginatum - sepals and petals bright yellow. 5-6 cm long. Loves to grow on shaded parts of raintrees. When the flowering period is here (Sep-Oct), the display of bright yellow spidery flowers engulfing the whole trunk of the tree is simply awesome.

 

 

My collection of bp vaginatum. Some I have potted them on potted them, others I have tied them to barks/blocks.
