Oncidium species are naturally found from Central and Southern America growing from sea level to an altitude of 3,000 m (10,000ft). 

They grow in well drained, moderately fertile moist bark and course material in a semi-shaded or bright indirect light. They require wind, frost and drought protection. 

These orchids are commonly known as Dancing Ladies and are popular potted plants or are planted in small or tropical gardens as a feature plant. They grow in a wide range of climate conditions and under culture require being placed in either a cool-house to warm-house depending on the species. ID 1152
