When first emerging from the soil, its pallid nubs can have the somewhat ghoulish appearance of stubby, dead fingers, lending it the common name “corpse plant.” The plant’s leaves have been reduced to small scales along its stems, which can appear singly or in dense clumps.  Each stem is tipped with a single, nodding bloom, forming the crook from which it derives its most common common name, “ghost pipe.” Bumblebees are a known pollinator and somewhat surprising sight in the forest depths these blooms inhabit, a testament to their industry in foraging. After pollination, the stem straightens, topped by a pointed seed capsule. In this wand-like form, the stems dry and persist into the following year, offering a clue as to the whereabouts of these perennials even when not in bloom.

Ghost pipes have a vast but irregular distribution across North America, northern South America, and Asia.  In the Pacific Northwest, look for them at relatively low elevation in deeply shaded gaps on the forest floor in conifer or mostly conifer woodland.
