Most varieties of passion fruit actually originally come from tropical regions in South America and Australia. However, under certain conditions, the plant can also produce ripe fruit in this country.

Prepare the passion fruit seeds for sowing

You can use special seeds from garden retailers to grow the plants. In this case, however, pay attention to whether they are varieties with edible fruits or Passiflora varieties grown purely for their flowers. You can take the seeds from the purple passion fruit or the yellow grenadillas, also known as passion fruit, and use them to grow young plants. However, you should first soak them in warm water so that you can remove the pulp before sowing. This is the only way to prevent the seeds from becoming moldy and also to prepare them for drying and storage that may be necessary. If you sow the seeds later and want to plant them in pots, you can keep them dried in air-permeable paper bags for a few months.

Germination and growth of passion flowers

Due to their origin in the tropics, the seeds of the passion fruit need a germination temperature of around 20 degrees Celsius and a consistently high level of moisture in the substrate. These conditions can be easily achieved with an indoor greenhouse on the windowsill. However, this should be ventilated regularly so that moisture does not build up and mold does not form. The seeds are only thinly covered with soil and should have germinated in about three weeks. Since only certain varieties can withstand temperatures below freezing for a short time, the season for passion flowers outdoors is limited to the period between spring and autumn. Over the winter, you should overwinter the passion flower, which is usually cultivated as a pot plant, in a frost-free and bright place. The plant sometimes lets certain parts of the plant die off, but sprouts new and larger ones from the rootstock in the spring.

Pollination of the flowers of passion flowers

Even with just one plant in the pot, you can get the passion flower to flower and produce fruit and seeds for further cultivation. Use a brush to dust the pistils of the self-fertile flowers with some pollen from the anthers.

tips and tricks

Since the passion flower (Passiflora) comes from frost-free areas, its seeds can be sown directly from the ripe fruit without waiting.
