By Sean O'Casey from a play of the same name. It's been recorded by a fair number of singers. Great song. Not a bad play either.

Here are the words from this site, which has a lot of Dubliners lyrics on it.

RED ROSES FOR ME
Sean O`Casey

A sober black shawl hides her body entirely
Touched by the sun and the salt spray of the sea
But down in the darkness a slim hand so lovely
Carries a rich bunch of red roses for me

Her petticoat simple and her feet are but bare
And all that she has is but neat and scanty
But stars in the deep of her eyes are exclaiming
I carry a rich bunch of red roses for thee

No arrogant gem sits enthroned on her forehead
Or swings from a white ear for all men to see
But jewelled desire in a bosom so pearly
Carries a rich bunch of red roses for me
