Feijoa sellowiana Berg is from the genus which the German botanist, Ernst Berger, named after João da Silva Feijó, a Portuguese naturalist, and the specific name honors Friedrich Sellow, a German who first collected specimens of feijoa in southern Brazil. The fruit, known as feijoa, matures in autumn and is green, ellipsoid, and about the size of a chicken egg. It has a sweet, aromatic flavour, which tastes like pineapple, apple, and mint. The flesh is juicy and is divided into a clear, gelatinous seed pulp and a firmer, slightly granular, opaque flesh nearer the skin. The fruit pulp resembles the closely related guava, having a gritty texture.
The feijoa pulp is used in some natural cosmetic products as an exfoliant. Feijoa fruit has a distinctive, potent smell that resembles that of a fine perfume. The plant is a warm-temperate, subtropical plant that also will grow in the tropics, but requires at least 50 hours of winter chilling to fruit, and is frost-tolerant. Some grafted cultivars of feijoa are self-fertile. Most are not, and require a pollinator. Seedlings may or may not be of usable quality, and may or may not be self-fertile.
