'aizoon' originates from Greek, specifically the word 'aizōon', where 'ai' meant 'always' and 'zōon' meant 'living'.

'aizōon' was adopted into Latin as 'aizoon', and eventually became the modern English word 'aizoon'.

Initially, it meant 'always living', referring to the plant's perennial nature, and this meaning has largely remained the same in modern usage.
