Native to the Southern United States, Passionflower, aka Passiflora Incarnata, is now widely cultivated throughout the US and Europe. Passionflower is often utilized for its gentle calming properties. This vining plant has showy, intricate flowers, which caught the eye of Spanish missionaries who correlated the inflorescence with the Passion of the Christ, and thus gave it the name passion flower. Passionflower can be tinctured, steeped as a tea, and incorporated into herbal infusions.
