In the language of flowers does a gladiolus mean
a) Give me another chance?
b) Don't touch me?
c) I will never forget you?
If you were to present someone with a bunch of gladioli (such as this Field Gladiolus it would mean a) Give me another chance. If you wish to say 'Don't touch me' you would use Burdock and if you wish to declare 'I will never forget you' then a pink Carnation would be appropriate.
