At just 8cm high it is our shortest orchid. Green all over it is well camouflaged amidst the grass and vegetation.

Compared to most other orchids, the flowers are upside-down, with the 2mm long lip (which lacks a spur) twisted around to the top.

The two leaves are elliptical and (not visible in the photograph) edged with tiny bulbils.


Some similarities (if you can find it) to :

  • Musk Orchid (Herminium monorchis) which is also green all over, but of a much lighter hue which smells not of musk but of honey and is taller at 15cm.
  • Fen Orchid (Liparis loeselii) which is rarer than Bog Orchid and again is yellowish-green and like bog orchid often has the un-spurred lip twisted around to the top. It is taller still at 20cm.
  • Common Twayblade (Neottia ovata) which at 60cm is even taller, but still yellowish-green. This orchid has a long and forked (again un-spurred) lip which hangs down in the normal poasition and is not twisted to appear on top as is Bog Orchid.
