“Flower in the crannied wall”

Flower in the crannied wall,
I pluck you out of the crannies,
I hold you here, root and all, in my hand,
Little flower—but if I could understand
What you are, root and all, and all in all,
I should know what God and man is.

–“Flower in the crannied wall,” a 1863 poem by Alfred, Lord Tennyson.
