Purple Passion Flower (Passiflora incarnata): Native Vine for Beauty and Calm

Purple Passion Flower (Passiflora incarnata, Maypop) is a fast-growing, herbaceous perennial vine native to southeastern U.S. Its exotic 3-5 inch flowers—white petals, purple filaments, intricate corona—inspired 16th-century missionaries to see Christian symbolism (10 petals/sepals = apostles, 5 stamens = wounds, 3 styles = nails, tendrils = whips). Beyond beauty, it offers edible fruit and herbal medicine.
