Ghost Orchid

Epipogium aphyllum

The Ghost orchid never grows leaves, and will therefore always depend on the fungus for its nourishment.

The Ghost orchid can live underground for years, without showing any external signs and will only bloom when all conditions are optimum. This explains why some orchid enthusiasts search for years and years just to have a glimpse of this elusive flower.
