Ode to the Violet…..

Roses are red,
violets are blue
but actually they're not,
let me tell you!
Violets are purple,
which is difficult to rhyme,
and to find the right word
has taken some time.
In fact I've given up
as it's really too hard,
for this amateurish poet
who's not exactly a bard.
So violets remain blue,
for the sake of tradition,
with their colour clarified
by this little rendition!
