“The rose of all the world is not for me.
I want for my part
Only the little white rose of Scotland
That smells sharp and sweet - and breaks the heart.”

To The Rose Upon The Rood Of Time http://poetry.poetryx.com/poems/1736/
The Rose (1893)
Context: Red Rose, proud Rose, sad Rose of all my days!
Come near me, while I sing the ancient ways:
Cuchulain battling with the bitter tide;
The Druid, grey, wood-nurtured, quiet-eyed,
Who cast round Fergus dreams, and ruin untold;

As translated in Spanish-American Poetry : A Dual-language Anthology (1996) by Seymour Resnick
Variant translation:
I cultivate a white rose
In July as in January
For the sincere friend
Who gives me his hand frankly. <p> And for the cruel person who tears out
the heart with which I live,
I cultivate neither nettles nor thorns:
I cultivate a white rose.

A White Rose, lines 1-4, in In Bohemia (1886), p. 24.
