Wolfberry is the common name for the fruit of two very closely relate species: Lycium barbarum (Chinese: 寧夏枸杞; pinyin: Níngxià gǒuqǐ) and L. chinense (Chinese: 枸杞; pinyin: gǒuqǐ), two species of boxthorn in the family Solanaceae (which also includes the potato, tomato, eggplant, deadly nightshade, chili pepper, and tobacco). Although its original habitat is obscure (probably southeastern Europe to southwest Asia), wolfberry species currently grow in many world regions. Only in China, however, is there significant commercial cultivation.
