I at last have a picture of the bloom of my passionfruit you sought
@pod.
I don't know if you know the story of the origin of the usage of "passion" here. (The history of plant nomenclature is very fascinating).
"The association with the word 'Passion' was given by Catholic missionaries in South America;
The corona threads (radial filaments) of the passion flower were seen as a symbol of the crown of thorns, the five stamens for wounds, (four by the nails and one by the lance);
The five petals and five sepals as the ten apostles (excluding Judas and Peter) and the three stigmas for the nails on the cross;
The pointed tips of the leaves were taken to represent the Holy Lance;
The tendrils represent the whips used in the flagellation of Christ;
The chalice-shaped ovary with its receptacle represents a hammer or the Holy Grail;
The blue and white colours of many species' flowers represent Heaven and Purity."
