Germination
To germinate Passiflora caerulea, start by rubbing the seeds with a piece of fine-grit sandpaper. Soak the seeds in warm water for 24 hours to help soften the seed coat. Then, plant the seeds in a well-draining potting mix or sandy soil in a container or seed tray. Sow the seeds at a depth of about 1/4 inch, and keep the soil consistently moist but not waterlogged during the germination process. Maintain a warm temperature of around 75-85°F (24-29°C) to encourage successful germination. Be patient, as passionflower seeds can take several weeks to several months to sprout. Once the seedlings are large enough to handle, they can be transplanted into your garden or larger containers.Â
