Solanum torvum (Turkey Berry), 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, Pea Eggplant, Pea Aubergine, susumba, boo, terongan, tekokak, berenjena cimarrona, berenjena de gallina, berenjena silvestre, tabacón, pendejera, tomatillo, bâtard balengène, zamorette, friega-platos, sundaikkai (Tamil: சுண்டைக்காய்), Thibbatu (Sinhala), makhua phuang (Thai: มะเขือพวง), and many other names (Howard 1989, Little and others 1974, Pacific Island Ecosystems at Risk 2001).
