Cactus flowers. (Photos by sard@rt)

As true delicacies of nature, cactus flowers are always a pleasant surprise.
The contrast between these colorful flowers that open wide to catch the sunlight and the threatening and painful thorns of the plant .. it has always fascinated me.

The cacti are very generous plants. They need little space, they ask us very little attention but they are able to give us moments of great beauty in return.
