S. nigrum subsp. nigrum
Solanum nigrum (Black Nightshade, Duscle, Garden Nightshade, Hound's Berry, Petty Morel, Small-fruited black nightshade, Sunberry, or Wonderberry) is a species in the Solanum genus, native to Eurasia and also introduced in the Americas. In Hawaii it is called popolo.
The green berries and mature leaves contain glycoalkaloids and are poisonous to eat raw. Their toxicity varies and there are some strains which have edible berries when fully ripe. The plant has a long history of medicinal usage, dating back to ancient Greece.
Black nightshade is a fairly common plant, found in many wooded areas, as well as disturbed habitats. It has a height of 30-120 cm (12-48"), leaves 4-7.5 cm (1 1/2-3") long; ovate to heart-shaped, with wavy or large-toothed edges. The flowers have petals greenish to whitish, recurved when aged and surround prominent bright yellow anthers. The fruits are oval black berries in small hanging clusters.
