Description
Solanum schenckii is a woodland species from central Mexico. Plants roughly 12 to 18 inches tall. Flowers violet to purple. Berries long and ovoid, green with white or lighter green spots.
The specific epithet, schenckii, honors Heinrich Schenck, who first collected the species. While there is no completely standardized pronunciation for scientific names, the most common way to pronounce this species is probably so-LAY-num SHENK-ee-eye.
