Naranjilla (Solanum quitoense) belongs to the Solanaceae (the Nightshade family). It is a perennial herb that is native to Ecuador, Peru and southern Colombia. This herb grows in brushwood in moist areas between 1600 and 2400 m elavation, and can reach 1.5-2.5 m in height. The stems are much-branched at the base. The leaves are large heart-shaped leaves up to 45 cm long and coarsely toothed. The acute spines are borne on the veins. The fragrant, white flowers bloom in the axils all year round. The fruits are round to oval-round, and ripen bright orange. Their pulps are green or yellow, very juicy and have a citrus flavour, sometimes described as a combination of rhubarb and lime.
