Answer

A wonderful and beautiful friend, named Basma, has just responded to my question as to why I document things I do not know.

Those flowers I photographed and posted minutes ago, are known as Japanese rose, seven-sisters rose, many-flowered rose, rambler rose. Botanically it is a Rosa multi-flora.

The answer is therefore, I document what I do not know in order to increase the chances of knowing what it is I documented.
