How to Grow Passion Flower Indoors

Updated November 21, 2016

Passion flowers are associated with mystique and intrigue. Christian missionaries named them in the early 1500s because they felt the passion flower symbolised the crucifixion of Christ. This plant will show its flower for only about a single day, adding to the sense that these tropical flowers are truly special and unique. There are over 400 species of plants that are labelled passion flowers, with most of them growing on vines. There are passion flowers that grow on trees, and some are considered shrubs, perennials or annuals and will produce edible fruit. Growing passion flowers indoors will add an exotic touch to your living space.

Choose a site in your home that will expose your passion flower to bright, but indirect sunlight and that is free of drafts. Keep the temperature in your home above 10 degrees Celsius at all times.

Provide nutrient-rich soil that drains well. The soil can have a neutral pH between 6 and 7.5. Add some compost to the pot to help retain moisture. Passion flowers need soil that is moist, but not soaking, to thrive. During the fall and winter, you can let the soil become nearly dry between watering.

Place your potted plant in a location where it has support and has some sort of structure, such as a banister or a counter top, to grow along. Passion flowers climb and grab on to things using their tendrils and may require some training to ensure they grow in the direction you desire. Vines will typically grow about 15 feet during a season and their blooming period is the middle or late part of the summer.

Prune your plant to remove dead wood in late winter or early spring. You can also prune to keep growth under control and to make your passion flower appear fuller.

Remove any leaves that become infected by a fungal disease such as leaf spotting. Use a fungicide to prevent spreading, if necessary. Purchasing healthy plants will also help you avoid disease.


To enjoy the bloom of the passion flower as a decorative plant, cut it off and drip melted wax at the base of petals. This will keep the flower open.
