Prehistoric

It is strange. In all these years, do not know how many but there are many, I have passed the Dutchman's pipe (Aristolochia macrophylla) that grows on a department store wall. And I have never seen the flower! Until today!
And now I understand why the plant has it Swedish name, "pipevine". The flower looks like a pipe! Almost like a prehistoric plant from the time of the dinosaurs.
