Oncidium |
|
Oncidium is a popular and varied genus of small to moderately large sized plants that produce flowers on upright racemes and panicles. Most Oncidiums are easy to grow and bloom. They enjoy moderately bright light, intermediate temperatures, good humidity and air movement. They grow well in plastic pots with moss or a seedling bark (Paph) mix. According to Dr. Robert Dressler, there are 37 species of Oncidium found in Panama. There may be more!
