Oncidium orchids have large pseudobulbs from which emerge long, mid green, strappy leaves that can often take on a drooping habit.
A stem will appear from a pseudobulb (just the once) upon which will be borne multiple, eye-catching flowers - generally with a large, protruding lower lip. They are very attractive and give the effect of a cloud of dancing butterflies.
Although from tropical climes, they do well in cooler climates as found in most parts of populated Australia and they are also popular as indoor plants.
