It's been a bumper year for orchids. The hot, dry spell in July-Aug stimulated flowering (I suspect it was more the light intensity rather than temperature that did the trick) and we're still reaping the results. Two other orchids that were induced was the SE Asian slipper orchid (Paphiopedilum, probably a hybrid) and the clamshell orchid.
The Diocentrum flowered twice this year (only the fourth occasion in ten years).

Paradoxically, the only orchid that didn't flower was the Phalaenopsis which is reputedly the easiest to cultivate indoors.
