Hammarbya paludosa. Bog orchid.

Life-form & Growth Form:

Hemicryptophyte. Herbaceous perennial. Little/no vegetative spread. Ramets detach from leaves.  

Flowering period: 

July and August.


Permanently wet bogs with typically acidic (but occasionally base-rich), slow-flowing water. Grows from bare peat and Sphagnum carpets, occasionally also among grasses and sedges, often on edge of or within runnels and flushes.  


Habitat loss and drainage, mainly as a result of peatland cutting and drainage. Overgrazing and poaching by livestock. Undergrazing can allow taller forbs and heath to shade out plants.
