Bird's Nest Orchid

Did you know

• The bird's nest orchid is entirely devoid of chlorophyll and cannot photosynthesize at all — it obtains 100% of its nutrition by parasitizing mycorrhizal fungi that are themselves connected to the roots of beech trees.
• The common name refers to the dense, tangled mass of fleshy roots that resembles a bird's nest — these roots are packed with fungal hyphae that the orchid exploits for sugars.
• Because it has no need for light, the bird's nest orchid can complete its entire life cycle in deep beech shade where no other flowering plant could survive — it emerges, flowers, and sets seed in near-complete darkness.
• The plant is entirely honey-brown to tawny in color from tip to root; the only greenish parts are traces in very sun-exposed individuals, where a small amount of chlorophyll can occasionally develop.
• Self-pollination is the norm in this species — in the absence of adequate pollinators in dark forest understory, the rostellum degrades rapidly and pollen falls directly onto the stigma.
