In bloom today (and most of the time)

Coelogyne usitana grows only on Mindanao. It is warm to hot growing. It will set a spike in spring or summer in new growth. A properly cared-for spike will bloom sequentially indefinitely.

The genus Coelogyne contains 100 species found in all of Asia east of India and Indonesia and Fiji. Conditions vary considerably.

This is a wonderful plant but a bit tricky to transport and display. The spike hangs down and keeps getting longer with each flower that opens. More than once I have knocked off part of a flower. As long as the last bud remains intact it will recover and continue blooming.

There is one particular thing to watch out for. Conventional wisdom says to wait until blooming stops to repot. With this plant one spike will likely still be blooming when the next growth period starts. These are best potted in sphagnum which should be changed every year or two.
