Bulbophyllum bicolor is lithophytic, sometimes epiphytic orchid found on rocky cliff faces in Hong Kong, Vietnam and South East China.
First identified in the early 1800s, it grows naturally in moss and leaf litter in these rocky areas usually near streams where it gets regular water in summer and spring with a little less in winter and autumn/fall.
The bi colour flower is distinctive, peachy pink with its red stripes. The tip off the dorsal petal has a furry edge, again red. This is not a fragrant orchid, but sought after for the unusual flowers.
Flower spikes develop sequential so Bulbophyllum bicolor will proved flowers over a number of months.
