The cashew tree is a tropical evergreen tree that produces the cashew nut and the cashew apple. It can grow as high as 14 metres (46 ft), with the exception of the dwarf cashew, which can grow up to 6 metres (20 ft). Its English name derives from the Portuguese for the fruit of the cashew tree caju literally meaning ânut that produces itselfâ while the name Anacardium, originally from the Greek, actually refers to the nut, core or heart of the fruit, which is outwardly located (ana means âupwardsâ and -cardium means âheartâ).
