What Is Passionflower?

Passionflower, also referred to as Maracuja or Maypop, is a genus of flowering plants in the family of Passifloraceae. It is found in the tropical rainforests and semi-tropical areas in South and North America, where it climbs up on other plants in the rainforest, using tendrils. There are over 500 species of passionflower vines, with the most common varieties found in the Amazon: passiflora edulis and passiflora incarnata.

Passionflower develops distinct, large, purple or white flowers that can be pink or purple in the centre. It was named by early Spanish missionaries, who thought that the appearance of parts of the flower represented the Crucifixion of Christ. Therefore, they called it “Flower of Passion”.

Some species of passionflower vine also produce a fruit about the size of a lemon, the passion fruit, which is also referred to as maracuja. Usually yellow or purple in colour, the fruit has a tough outer rind and a seedy centre and is well-known (Ingale & Kasture, 2017)  for its high antioxidant content. The pulp of the fruit can be eaten or can be used to make drinks, sherbets and jams.

How Passionflower Got Its Name

Christian scholars described the flower as “La Flor de las cinco Llagas” (the “Flower with Five Wounds”), or “Flower of Passion”, as references to the passion and wounds of the Christ. For them, the five petals and the five sepals of the plant represented the 10 faithful apostles (excluding the not-so-faithful Peter and Judas), and the tips of the leaves resembled centurion’s spear. The central flower was a symbol for the pillar of the scourging and the tendrils of the plant resembled the whips used in the flagellation. The corona filament had been compared to the crown of thorns with the three stigmas of the plant representing the nails. The five anthers stood for the five sacred wounds and the red stains of the flower symbolized the blood of Christ.

Later, in 1745, Swedish botanist Linnaeus gave the plant the Latin name “Passiflora”, which is the name that is still used for the genus today.

How To Plant Your Passionflower

Passionflower does best if you plant her in spring, in fertile, well-drained soil. The best way to go about planting would be if you get the plants from a nursery, although you could in principle also grow them from seed or from cuttings.

For planting, dig a large hole, about three times the diameter of the root ball. Take the plant out of the pot it came with and use a hose to wash the root ball, so that the roots are exposed. Carefully place the root ball into the hole and fill with your potting soil. Water, and afterwards also make sure to keep the flowers well-watered at all times.

If you don’t live in a tropical climate, you should bring the plants indoors during winter. The plants will show off their gorgeous flowers late in the summer.
