North American plants of damp places ranging from moist valleys in the Prairies to high mountain meadows of the Rockies and western ranges, even up to the Arctic. Around 30 species, resembling each other, but with a range of heights. Colour ranges from white to rose and purple. Their beauty come from the down turned, dart-like flowers, poised on short arching stalks, which spring from atop each stem. Basal clumps of smooth, sometimes bronzey coloured, foliage are also rather neat.
