The stems of rosy twisted stalk are usually single and unbranched, rising 15-30 cm high from underground rhizomes. The leaves alternate along the stems and are oval to elliptical in shape with parallel venation. They measure from 5-9 cm long and 2-4.5 cm wide and do not clasp the stem (as those of clasping-leaf twisted stalk do) at their base.
The flowers are suspended below the stems on straight, thin pedicels from 9-20 mm long. The flowers are rose or reddish in color, tipped with white or greenish-yellow. The tepals are narrowly oblong-lanceolate in shape, spreading only slightly at the tips. The 6 stamens are several millimeters shorter than the tepals. The fruit is a bulbous , oblong red berry 5-6 mm long.
Rosy twisted stalk may be found in moist woods and along streambanks between elevations of 3000'-6000'.
Rosy twisted stalk may be found from Alaska south through the coastal mountains (including the Olympics) and Cascade Mountains to northern Oregon. It is found eastward to southeastern British Columbia.
In the Columbia River Gorge, it may be found between the elevations of 2900'-4400' from Silver Star Mountain east to near Mount Defiance.
