It is a herbaceous perennial plant growing to 40-100cm tall, with alternate, oblong-lanceolate leaves 5-14cm long. The greenish-white flowers hang from axils on 1-2cm thin kinked panicles, each flower with six white tepals, 9-15mm 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.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.

Streptopus amplexifolius is widely distributed across North America (Greenland, northern United States including Alaska; and most of Canada including Yukon and Northwest Territories). The plant is most often found near shaded stream banks and in moist thickets of the montane and subalpine zones across most of North America. It is also found in central and southern Europe (from Spain to Ukraine and as far north as Germany and Poland) and in eastern Asia (Japan, Korea, Myanmar (Burma) and eastern Russia (Yakutia, Amur, Kamchatka, Sakhalin, Kuril Islands, Khabarovsk, Primorye)).
Streptopus amplexifolius was used as a food plant by Native Americans in Eastern North America and as a medicine. The plant was referred to by early settlers of Eastern and Western North America as "wild cucumber" and as "scoot berries" for the mildly laxative effects of the berries if they are eaten in excessive quantities.
The tender young shoots of this plant were eaten by some aboriginal peoples as a salad green, but most considered the plant and berries poisonous. The shoots are sweet with a cucumber-like flavor. The berries are reported to be juicy and sweet, with a watermelon-like flavor. The juice of the berries was used as a soothing treatment for burns by American Indians.
Streptopus amplexifolius has a superficial resemblance to False Solomon's Seal (Maianthemum racemosum), but Twisted Stalk produces axillary flowers and fruits along the stem, where False Solomon's Seal produces a terminal inflorescence. Also False Solomon's Seal is always a single unbranched stem, while Twisted Stalk can be branched at the bottom. In fruit, Twisted Stalk is easily identified by its large, juicy red berries which grow from each leaf axil and are highly visible, even in the thickest undergrowth, as they boldly contrast with the surrounding foliage.
When young, Twisted Stalk resembles members of the genus Veratrum, highly toxic plants that are members of the lily family, also. This plant should not be consumed unless identification is positive.
