Slipper Plant Seeds:
Guide to Storing, Sowing and Germination

Updated: July 4, 2023

Slipper plants, also known as Calceolaria, are a unique and beautiful addition to any garden. With their vibrant colors and distinctive slipper-shaped flowers, these plants are sure to catch the eye of any gardening enthusiast. One of the best ways to grow slipper plants is by starting them from seeds. In this article, we will guide you through the process of storing, sowing, and germinating slipper plant seeds.

Storing Slipper Plant Seeds

Before sowing slipper plant seeds, it’s essential to ensure that they are stored properly. Proper storage will help maintain the viability of the seeds over time. Here are some tips for storing slipper plant seeds:

  1. Harvesting seeds: To collect slipper plant seeds, wait until the seed pods turn brown and begin to split open. Gently remove the pods from the plant and collect the small black or brown seeds inside.

  2. Drying: Lay the seeds out on a paper towel or a screen in a single layer. Allow them to air dry for about a week in a cool, dry location away from direct sunlight. Make sure the seeds are completely dry before moving on to the next step.

  3. Container selection: Choose an airtight container for storing your slipper plant seeds. A small glass jar with a tight-fitting lid works well. Ensure that the container is clean and dry before adding the seeds.

  4. Labeling: Before sealing the container, it’s crucial to label it with the plant’s name and the date of collection. This information will help you keep track of your seed collection and determine their viability in the future.

  5. Storage conditions: Store the container in a cool, dark place such as a refrigerator or a basement. The ideal temperature for slipper plant seed storage is around 40°F (4°C). Avoid exposing the seeds to extreme temperatures or moisture, as it can reduce their viability.

By following these steps, you can store slipper plant seeds for up to three years while maintaining their quality.

Sowing Slipper Plant Seeds

Once you’re ready to sow your slipper plant seeds, it’s essential to choose the right time and method for sowing. Here’s a step-by-step guide to help you get started:

  1. Timing: Slipper plant seeds are best sown in late winter or early spring, approximately six to eight weeks before the last expected frost in your area. This timing allows the seedlings to establish before transplanting them outdoors.

  2. Seed tray preparation: Use a seed tray or small pots with drainage holes for sowing slipper plant seeds. Fill the containers with a well-draining potting mix that is specifically formulated for starting seeds.

  3. Sowing: Gently press one or two slipper plant seeds into each pot or cell of the seed tray. The seeds should be covered with a thin layer of soil, approximately the same depth as the seed’s size. Mist the soil lightly with water to settle it.

  4. Moisture and temperature: Slipper plant seeds require consistent moisture and warmth for germination. Cover the seed tray or pots with plastic wrap or a clear plastic dome to create a humid environment. Place them in a warm location where the temperature is around 70°F (21°C).

  5. Watering: Keep the soil consistently moist but not waterlogged. Use a spray bottle or misting wand to water the seedlings gently, as strong streams of water can dislodge the seeds or disturb their delicate roots.

  6. Germination: Slipper plant seeds typically germinate within two to three weeks. Once the seedlings emerge, remove the plastic cover and place them in a bright location where they can receive indirect sunlight for at least six hours a day.

By following these steps, you can ensure a successful start to your slipper plant seeds.

Germination and Care

After the slipper plant seeds have germinated, it’s vital to provide them with the care they need to thrive. Here are some tips for nurturing your slipper plant seedlings:

  1. Light: Slipper plants require bright but indirect sunlight. Place the seedlings near a south-facing window or use artificial lighting, such as fluorescent grow lights, if natural light is insufficient.

  2. Temperature: Maintain a temperature of around 65-70°F (18-21°C) during the day and slightly cooler temperatures at night. Avoid exposing the seedlings to extreme temperature fluctuations.

  3. Watering: Keep the soil consistently moist but not waterlogged. Water the plants when the top inch of soil feels dry to the touch. Avoid overwatering, as it can lead to root rot and other issues.

  4. Fertilization: After the seedlings develop their first set of true leaves, begin fertilizing them with a balanced, water-soluble fertilizer diluted to half strength. Apply the fertilizer every two weeks throughout the growing season.

  5. Transplanting: Once the seedlings have grown two to three sets of true leaves and all risk of frost has passed, they can be transplanted into larger pots or directly into the garden. Ensure that the soil is well-draining and amend it with organic matter if needed.

With proper care and attention, your slipper plants will reward you with their unique beauty and vibrant blooms.

In conclusion, growing slipper plants from seeds is an exciting and rewarding experience for any gardener. By following the guide to storing, sowing, and germinating slipper plant seeds outlined in this article, you’ll be well on your way to enjoying these stunning plants in your garden. Happy gardening!
