Passiflora caerulea - blue passion flower by Lesley Catchpole

Passiflora caerulea, commonly known as Blue Passionflower, is a climbing vine native to South America, known for its striking flowers. Passionflower extracts have long been used to ease anxiety, improve sleep, and soothe nervous tension. Some indigenous cultures also used it as a remedy for mild pain and digestive discomfort. The name ""Passiflora"" comes from early Spanish missionaries who saw in the flower’s structure a representation of the Passion of Christ - the radial filaments symbolising the crown of thorns, the five stamens representing Christ’s wounds, and the three stigmas reflecting the nails of the crucifixion. Beyond its Christian associations, the passionflower has also been regarded as a symbol of peace, enlightenment, and spiritual transformation.
