Harvest Tips
Oncidium orchids are ornamental flowers, not harvested for consumption.

Allow plant to rest 4-8 weeks post-bloom before next growth cycle.
Fun Facts
- 🌱 Miniature Oncidiums are nicknamed 'Dancing Lady orchids' because their delicate flowers resemble tiny ladies in ballroom gowns, particularly the central lip that looks like a full skirt in motion.
- 🌱 Oncidium orchids have evolved intricate relationships with specific bee species; the flower's shape and color patterns mimic female bees, attracting males through pseudo-pollination—a fascinating example of plant-insect deception in nature.
- 🌱 Miniature Oncidiums can produce 50+ flowers on a single inflorescence, making them prolific bloomers; some cultivars flower multiple times per year when grown in ideal conditions with proper light and seasonal temperature variation.
