The red tulip symbolizes a declaration of love in the Victorian's floral language... I'd like to take that a bit further.
O lips full of lust and of laughter,
Curled snakes that are fed from my breast,
Bite hard, lest remembrance come after
And press with new lips where you pressed.
For my heart too springs up at the pressure,
Mine eyelids too moisten and burn;
Ah, feed me and fill me with pleasure,
Ere pain come in turn.
By the hunger of change and emotion,
By the thirst of unbearable things,
By despair, the twin-born of devotion,
By the pleasure that winces and stings,
The delight that consumes the desire,
The desire that outruns the delight,
By the cruelty deaf as a fire
And blind as the night,
By the ravenous teeth that have smitten
Through the kisses that blossom and bud,
By the lips intertwisted and bitten
Till the foam has a savour of blood,
By the pulse as it rises and falters,
By the hands as they slacken and strain,
I adjure thee, respond from thine altars,
Our Lady of Pain.
Algernon Charles Swinburne, from Dolores (Notre-Dame Des Sept Douleurs)
