The lily has a smooth stalk,
Will never hurt your hand;
But the rose upon her briar
Is lady of the land.
There's sweetness in an apple tree,
And profit in the corn;
But lady of all beauty
Is a rose upon a thorn.
When with moss and honey
She tips her bending briar,
And half unfolds her glowing heart,
She sets the world on fire.

Christina Georgina Rossetti
