What are passion flowers?

Passion flowers are a large group of plants with many different species that primarily grow in tropical and subtropical regions. Most Passiflora are climbing plants that use tendrils to grow up trellises, fences, or other forms of support. This means they do not just stand still like a traditional houseplant, but grow and develop continuously. Under the right conditions, they can quickly take up space and create a green and vibrant look.

Some species are grown primarily for their flowers, while others can also develop fruits – including edible passion fruits.

Passiflora sp.

  • A plant with character and movement

    What makes passion flowers special is both their blooms and the way they grow. They are not static plants, but move actively as they form new shoots and wind their way up their surroundings.

    This makes them ideal for:

    • Window sections
    • Conservatories
    • Patios during the summer months


    Places where they are allowed to climb
    At the same time, they provide a more natural and slightly wild look, which distinguishes them from many more controlled houseplants.

  • Care of Passiflora

    Passion flowers are not necessarily difficult to care for, but they require a little more attention than many common houseplants.

    The most important things are:

    • Plenty of light
    • Something to climb on
    • Regular watering without the soil becoming too wet
    • Fertilizer during the growing season with good organic fertilizer


    Since they grow quickly, they also have a greater need for space and support. At the same time, most species do not tolerate frost and should therefore be kept in pots so they can be moved indoors during the cold months. Once you understand the plant's growth, it is both lively and rewarding to work with.
