Description

  • Spindly plant that is easily overlooked ~40 cm tall but tends to appear shorter since it often grows in sphagnum.
  • Tiny white flowers.
  • May gain some nutrients from soil fungi.

Habitat

  • Found in peat soils in sphagnum bogs, fens, and low shrub bogs, where trees such as Tamarack and Black Spruce grow.

Threats

  • Populations are isolated and only one is located on crown land (conservation reserve)
  • Invasive shrubs such as black buckthorn.

Conservation Actions

  • Bog and fen habitat is important for this plant and other species like the endangered spotted turtle. Support efforts to help maintain these types of wetlands.
