I was amazed when I discovered that the three-part pistils of the Passion Bloom lift up when it rains.
My hypothesis is to prevent self-fertilization from splashing pollen. No time to research that today, but I know one of you knows so leave a comment.
Absolutely LOVE this vine.

Great observation. Does yours come back after a freeze?

I googled the question and the only sources about Passion pistils were by floweralley.org.

I am fascinated by these flowers, too. Probably a George Rogers question.

Can’t help you with that one but will watch mine closely when it starts to flower. I have two different ones in the garden and nurture a P. incana in the greenhouse.
