Nodding Greenhood Neil Blair/RBGV

Nodding Greenhood

Flowering orchid up to 30 cm tall.

This orchid is pollinated by a species of fungus gnat, attracted to the flower by a chemical produced by the plant. The insect enters the flower, which temporarily traps it inside, and in attempting to escape, it comes into contact with the sexual organs of the flower and pollination occurs.


Egg-shaped to elliptic dark-green leaves in rosette arrangement at the base of the stem, 3 – 9 cm long, 1 – 3 cm wide. Leaf margins wavy or crisped.


Single flower ‘hood’ emerging on a flowering spike 8 - 30 cm tall. Flowers are 1.8 – 2.5 cm long, showing a strong ‘nodding’ position; and are a translucent white colour, with green stripes and orange/brown colouration at the tips.

Climate Adaptations

By virtue of their sensitivity to the changes in the climate, epiphytes and orchids provide a forewarning about impending damages and act as bio-indicators.
