Habitat:Calopogon tuberosus, grass pink orchid, Dirty Botany

Calopogon tuberosus loves wetlands!

During early summer you can find Calopogon tuberosus in bogs, swamps, edges of wetlands, wet meadows, fens, and even disturbed habitats. Look for things like cotton sedge, sundew, leatherleaf, or cranberries, which all can be found in similar habitats.
Oftentimes you will see Rose pogonia (Pogonia ophioglossoides) or even Arethusa bulbosa (dragon’s mouth orchid) growing alongside them.

You can find Calopogon tuberosus in all of the New England states. It is ranked S3 in Vermont and Rhode Island, and is stable in the other states.
