How do you grow passion flowers indoors?

There are more than 400 species of tropical passion flowers (Passiflora spp.) ranging in size from ½ inch to 6 inches across. They are found naturally from South America through Mexico. Early missionaries in the region used distinctively colored patterns of flower parts to teach about Christ’s passion; Hence the name.

The passion flower gets its name from the unique structure of its flowers and their symbolic importance. According to the original catalog of plants, each structure of the flower is religious in nature: the corolla reflects Christ’s crown of thorns, the five stamens represent the five wounds on his hands, feet, and side, and the three stigmata. Christ was used to nail the cross.

Whatever their religious significance, there’s no question that passion flowers are beautiful and whimsical, especially among the most commonly grown houseplants, p. Caerulea. But make no mistake: growing a successful passion flower is like catching a tiger’s tail. They are sturdy, sprawling vines in ideal conditions that may require frequent pruning to stay well behaved.

Tips for Passion Flower Care

The tops will die off in the winter, but if you mulch deeply, your passion flower plant will come back with new shoots in the spring. Since growing passion flowers can reach 20 feet in one season, this dieback will help keep vines under control. According to Deltona Arborists for Garden Care, tropical passion flowers need full sun and well-drained soil. Two applications of a balanced fertilizer per year, once in early spring and one in mid-summer is all the passion flower care you need.

Growing conditions

  • Light: Bright light, especially during the summer growing season. Full sun is preferred in summer, as much light as you can in winter.
  • Water: Keep plants moist at all times during the growing season and you may need to water larger plants twice a day in the summer. In winter, reduce watering but don’t let it dry out.
  • Temperature: Warm in the summer (household temperatures are fine) and cold in the winter months (up to 50˚F at night). They are usually hardy, and even if they die to the ground, they will likely recover the following spring.
  • Soil: A rich, quick-draining mixture is ideal.
  • Fertilizer: Fertilize adequately during the growing season with controlled-release fertilizers and liquid fertilizers.


Passionflower is easy to propagate by leaf tip cuttings. Take cuttings in spring. Strip off a few leaves to expose the nodes and bury the cuttings in moist seedling-starting soil.


Repot young plants into a larger pot each spring. Old plants can be stretched every few years between repotting. To control their size, it’s best to cut back your passionflower in the fall, leaving a few vines between 15″ and 20″ tall in the container. However, be aware that plants pruned this way still need to be repotted or at least refreshed.

Tips for Growers

Passion flower vines have deeply lobed leaves that hang from the flowers or peek out from the leaves.

Some species have edible fruit, which is a sweet and delicious tropical fruit. As vines, they can pose a challenge for indoor growers. Outdoors, passion flowers grow on walls, fences and trellises, where they are frequented by many types of butterflies. Indoors, however, their sprawling vines can be a nuisance. A particularly effective way to manage their growth is to train the vines around a wire support, such that a loop of wire forms a giant oval over the pot. As for pests, the biggest danger is usually mites or mealybugs. Both can be controlled with insecticidal soaps. Finally, passion flowers are prolific growers throughout the growing season and benefit from plenty of sun, water and fertilizer, as well as frequent pruning, which can stimulate even more blooms.
