Record

Narration
0:00 / --:--

It blooms only the few minutes the fog passes.

Miss those minutes, and the flower has already closed.

The Atacama, the driest desert on earth.

On gravel touched by fog climbing from the sea, the Hourglass Flower appears.

Clad in fine silver hairs, it spreads over the ground like a low cushion.

When fog touches its leaves, a white saucer flower opens, flushed with pink.
