In the cracks of the marble floors, in the crannies of the walls, springing from beneath the broken statue, voiceless yet persistent, grow scarlet poppies — the sleep flowers of the world, yielding to this yellowing Temple of Mysteries the quieting influence of their presence.

The sleep-flower sways in the wheat its head,
Heavy with dreams, as that with bread:
The goodly grain and the sun-flush'd sleeper

There were poppies everywhere — red and white and yellow, in groups and clusters, hanging their drowsy heads in the noonday sun which still seemed robbed of half its power here.
"Sleep-flowers, you know," said Mary, who was an authority on these matters.

The Digger tribe of Indians in California, whose nomad traditions have long since been seared out of existence by the white man's scorn, have held to the legend of the tiny crimson poppies that grow on the edge of the desert in the spring. They are called "sleep flowers" and the story goes that he who lies among them for even a little while will be visited forevermore by a spirit who will drag him each night to that same spot.

It was not for a sacred cause,
Nor for faith, nor for new generations,
That unburied we roll and float
Beneath this flaming tumult of drunken sleep-flowers.

Strange fellowship of Nature! I had snared
On that wold's height a memory to keep
Of sleep-flowers and an ever-chanting bird—
Poppies by Lethe known, a lark's song heard—
The lord of waking and the lords of sleep.
