月下美人　Dutchmans pipe cactus , A Queen of the Night

The flower named Gekkabijin was in bloom very slowly tonight.
The English name is “ Dutchmans pipe cactus, A Qeen of the Night”.
This flower bloom only one night in a year.
Last summer we could not see the moment beginning to bloom.
Fortunately my wife took some shots of the flower.
Why do they call the name as “Dutchmans pipe cactus”?
Do you know this question?
