Fun Facts
- 🌱 Orchids are one of the largest plant families with over 25,000 species and 100,000+ registered hybrids, found on every continent except Antarctica.
- 🌱 Some orchid flowers mimic female insects so convincingly that male insects attempt to mate with them, transferring pollen in the process—a strategy called sexual deception.
- 🌱 Orchid seeds are incredibly tiny (no larger than dust) and contain no endosperm; they require mycorrhizal fungi to germinate, making natural propagation extremely difficult.
