'Passiflora caerulea' is a climbing plant with beautiful ivory-blue passion flowers. This is the most well-known species because it is best suited to our climate and is reasonably hardy. From June to September you can expect flowers in the passiflora. The passion flower is a real nice weather bloomer. On warm days with lots of light/sun the buds will burst open. On colder and darker days, few flowers will burst open. It is a real climber and therefore likes some support when growing on a climbing frame or fence.
