Fun Facts
- 🌱 Oncidiums are called 'dancing lady' orchids because their petals resemble the skirt of a woman dancing—the large lip (labellum) appears to be a lady in motion.
- 🌱 Small Oncidiums can flower multiple times per year with proper care, producing hundreds of blooms from a single plant, making them excellent value as houseplants.
- 🌱 Oncidiums are epiphytic orchids that naturally grow on trees in tropical rainforests, which is why they require excellent air circulation and free-draining bark medium rather than traditional soil.
