Color of a Rose

Would a rose be as sweet
If its pedals were as green as the grass
It lives upon?
Or is red,
Love in its colored form,
More befitting for such a delicate being?
A gift of love is a rose
When it is blood red.
Or, perhaps, is pink,
By reason of its ability to show
The youthful spirit of the flower,
Favored among the people of the earth?
A yellow rose does shine and sparkle
Like the sun
Whose beauty shall never be surpassed
Even by an elegant flower.

I do wonder, if by any chance,
A rose could be colored blue.
Would it have the same effect?
Would it be as romantic?
Or can any rose,
No matter how uniquely stained,
Be able to excel the beauty-
And romance-
Of one that is red?
