I wasn't sure that the non hardy passion flower would bloom this year. It had been somewhat neglected since mom passed away. We were careful to water it, and put it on the east side of the shop so it would get gentle sun. About two weeks ago, it sprouted a tiny bud. I was very excited. I have been watching it carefully since them. Today it bloomed! It went from barely showing color to fully opened within 2 hours. Simply amazing. The flowers only last a single day, so you have to be quick if you want a picture. What a beautiful and strange flower. Here is a progression from bud to flower. I think this will be the only flower for this plant this year. I can't find any other buds. Maybe next year it will be more generous.
Here is the other type. The differences are striking.
