A neighbor gave me cuttings of their passion vine a few years ago. In our zone, it comes back every year after going dormant in the winter. You know summer is in full swing when the vines burst into bloom. The flowers are amazing and the scent divine. Passion flowers were named for the passion of Christ. The filaments represent the crown of thorns, the ten petals are the ten faithful apostles, the five anthers the five wounds, and the stigmata represent the three nails.
