Streptopus amplexifolius

Streptopus amplexifolius (twistedstalk, clasping twistedstalk, claspleaf twistedstalk, white twisted-stalk, or watermelon berry) is a species of flowering plant in the family Liliaceae, native to North America, Europe and Asia. It is a herbaceous perennial plant growing to 40–100 cm tall, with alternate, oblong-lanceolate leaves 5–14 cm long. The greenish-white flowers hang from axils on 1–2 cm thin kinked pedicels, each flower with six white tepals, 9–15 mm long. The plants leaves completely encircle the stem, and the stems have a kink at each leaf axil giving the plants stem a "twisted" and wiry appearance. The plants grow in a creeping habit in moist, dense undergrowth....read more on Wikipedia.
