Pea eggplant (Solanum torvum ), is a bushy, erect and spiny perennial plant used horticulturally as a rootstock for eggplant. Grafted plants are very vigorous and tolerate diseases affecting the root system, thus allowing the crop to continue for a second year.
It is also known as Devil's Fig, Prickly Nightshade, Shoo-shoo Bush, Wild Eggplant, Turkey berry, Pea Aubergine, Susumber (in Jamaica) and many other names (Howard 1989, Little and others 1974, Pacific Island Ecosystems at Risk 2001).
