The roselle (Hibiscus sabdariffa) is a species of Hibiscus native to the west Africa, used for the production of bast fibre and as an infusion. It is an annual or perennial herb or woody-based subshrub, growing to 2?2.5 m (7?8 ft) tall. The leaves are deeply three- to five-lobed, 8?15 cm (3?6 in) long, arranged alternately on the stems.

Watermelon (Citrullus lanatus, family Cucurbitaceae) is a vine-like (scrambler and trailer) flowering plant originally from southern Africa. Its fruit, which is also called watermelon, is a special kind referred to by botanists as a pepo, a berry which has a thick rind and fleshy center (mesocarp and endocarp). Pepos are derived from an inferior ovary, and are characteristic of the Cucurbitaceae. The watermelon fruit, loosely considered a type of melon – although not in the genus Cucumis – has a smooth exterior rind (green, yellow and sometimes white) and a juicy, sweet interior flesh (usually deep red to pink, but sometimes orange, yellow and even green if not ripe).

Olive oil is a liquid obtained from olives (the fruit of Olea europaea; family Oleaceae), a traditional tree crop of the Mediterranean Basin. The oil is produced by pressing whole olives. It is commonly used in cooking, whether for frying or as a salad dressing.It consists mainly of oleic acid (up to 83%), with smaller amounts of other fatty acids including linoleic acid (up to 21%) and palmitic acid (up to 20%).
