Pretty Poison

When people think of a valentine flower, they usually think of roses, and red ones at that. That is because the rose is a symbol of love. In honor of said tradition and floriculture's use of pesticides, I thought it was the perfect opportunity to pen a variation of the Roses are red poem:

Roses are red,
Violets are blue,
These have been sprayed with pesticides,
And can be harmful to you.

My vote is for the exchange of love notes or chocolates. Any questions?
