First saw this species at the Brooklyn Botanical Gardens over 10 years ago & have been intrigued & obsessed w/it ever since…so it’s great that my neighbor, Jean, planted a vine that is thriving:) Passion Flowers grow on  climbing vines..during their blooming season, the flowers start to open slowly…some varieties open later in the day and then close at night. So each day is a surprise. She had just watered the vine with an old fashioned large round sprinkler head. I just love photographing this flower.
