Streptopus lanceolatus (rose twisted stalk, rosybells, rose mandarin, scootberry, liverberry, rose-bellwort), is an understory perennial plant native to the forests of North America, from Alaska to Labrador, south through the Great Lakes and Appalachian Mountain regions of the United States , as well as Montana, Washington (state) , Oregon, and St. Pierre & Miquelon.[2][3] It grows primarily in mixed-wood forests, and throughout a wide range of soil and site conditions, preferring cool, acidic soils.

Streptopus lanceolatus grows from a rhizome or seed, the stem having a zigzag shape, branched or sometimes unbranched. Up to 30 cm (12 in) tall with alternate wide lanced oval-shaped leaves with pointed tips and a rounded base, without leaf-stalks. The leaves are often finely toothed having fine hairs on the underside veins. Flowers appear as solitary individuals opposite each leaf in early summer (May to July) and are bell-shaped on 1–3 cm (0.4–1.2 in) long stalks bent midway, with 6 rose or white recurved petals with purple streaks. Fruit is an elongated red berry ripening in mid-summer (July to August). If berries are consumed in quantity, diarrhea can result.[2][4][5]

Streptopus lanceolatus can be distinguished from Solomon's seal and false Solomon's seal by the alternate leaves on a zigzag stem.
