Passiflora incarnata, commonly known as maypop, purple passionflower, true passionflower, wild apricot, and wild passion vine, is a fast-growing perennial vine with climbing or trailing stems. A member of the passionflower genus Passiflora, the maypop has large, intricate flowers with prominent styles and stamens. The stems can be smooth or pubescent; they are long and trailing, possessing many tendrils. Leaves are alternate and palmately 3-lobed and occasionally 5-lobed, measuring 6–15 centimetres (2.4–5.9 in). They have two characteristic glands at the base of the blade on the petiole. Flowers have five bluish-white petals.
Historically, the plant has been used as a herbal medicine in the belief it may be used for anxiety, insomnia, or hypertension. In traditional medicine, passionflower is reputed to have a number of potential uses including diarrhoea, dysmenorrhoea, neuralgia, burns, haemorrhoids and insomnia as used historically in Europe,
