'alyssum' originates from Latin, specifically the word 'alysson', where 'a-' meant 'without' and 'lyssa' meant 'rage' or 'madness'.

'alysson' transformed into the French word 'alysson', and eventually became the modern English word 'alyssum' through Middle English.

Initially, it meant 'a plant believed to cure madness', but over time it evolved into its current meaning of 'a flowering plant'.
