Bud Formation
4-6 weeksFlower spikes emerge from leaf axils or base of pseudobulbs; small buds visible along spikes

Fun Facts
- 🌱 Oncidium equitans gets its species name 'equitans' from the Latin word for 'riding,' referring to how the leaves overlap and clasp each other like a rider on horseback.
- 🌱 This orchid is an epiphyte, meaning it naturally grows on tree branches in rainforests rather than in soil, which is why it requires such specialized, well-draining growing media.
- 🌱 Oncidiums are sometimes called 'dancing lady orchids' because their flowers resemble the skirts and posture of a dancing woman, making them among the most whimsical orchid species.
