Rosy Roses and Violet Violets

Roses are red
Violets are blue...
Except when they're yellow
They both can be white too   

 

Roses can be rosy
Violets can be violet
Any color you desire
There's one for each palette

Sometimes they are lavender
And lavenders are lavender
So if violets are lavender
What are violet lavenders?

If you wish to bid farewell
Or deliver a death threat
Nothing like a jet black rose
To induce a little sweat

Peachy roses are peachy
Sincerity it conveys
Just gotta find the one girl
Who wouldn't laugh in your face

Roses are dear
Violets are cheap
If I spend a little more
Would you let met watch you sleep

Red roses and blue violets
Deathly unoriginal
Here's a pretty hybrid rose
Red-blue hue for my lovely beau
