Roses are blue
Violets are Pink
Oh great!
My monitor's on the blink

Serke na carnë,
Nen na luinë.
Silain elyesse,
An si avan.

Blood is red,
Water is blue.
In you may I shine,
For now I (must) pass on.

Roses are red,
Violets are blue,
But did you know?
They grow in horse poo!.

[Edit]

I Always thought voilets was more kinda voilet kinda colour? oh well =p

Yes, they are, but lotuses don't fit in the metrum.

Aren't lotuses (loti?) pink?
