Passion flower, from the family Passifloraceae, is a tropical flower which features bright, beautiful blooms. Passion flower grows on every continent except Europe and Antartica. Nine varieties of this flower are native to the United States. Missionaries named the flower because they thought it looked similar to the crown of thorns worn by Jesus Christ during the Passion, which was the period of suffering that occurred after the Last Supper prior his death by crucifixion.
This flower is often compared to valerian because of its relaxing effects on the nervous system.
