Fun Facts
- 🌱 The name 'Oncidium' comes from the Greek word 'onkos' meaning 'swelling,' referring to the prominent lip (labellum) found on these orchid flowers.
- 🌱 Gower Ramsey is a hybrid that combines traits from multiple Oncidium species, bred for superior vigor and blooming ability compared to species orchids; it's one of the most reliable Oncidiums for home growers.
- 🌱 Oncidium flowers are pollinated by male bees in nature, which are attracted by the flower's pheromone-like scent and patterns; the bee attempts to mate with the flower, transferring pollen in the process (pseudocopulation).
