Would you recognize this flower?
It is edible, the caper, but especially the fruit, the caper berry that is very much used in italian and Mediterranean gastronomy.
The flowers are delicate and the light during the day changes slightly the colors,
The plant needs a semiarid climate, lots of daylight and sun to offer a good harvest. It is also used as a cover ground, but will not tolerate frozen temperatures. Here is the plant covering a wall and used as ornamental in a friend's garden.
