Heart Plant Seeds:
Guide to Storing, Sowing and Germination

Updated: June 29, 2023

Introduction

Heart plants, also known as dicentra or bleeding hearts, are beautiful flowering plants that are popular in gardens due to their unique heart-shaped flowers. These plants can be grown from seeds, making them a great option for gardeners who want to start their heart plant journey from scratch. However, it’s important to know the proper methods for storing, sowing, and germinating heart plant seeds to ensure successful growth. In this guide, we will take you through the step-by-step process of handling heart plant seeds.

Storing Heart Plant Seeds

Storing heart plant seeds properly is essential to maintain their viability. Here are some guidelines to follow when storing heart plant seeds:

  1. Harvesting Seeds: To collect heart plant seeds, wait until the seed pods have dried on the plant. The seed pods will turn brown and become brittle when they are ready to be harvested. Carefully remove the seed pods from the plant and place them in a paper bag or envelope.

  2. Drying Seeds: Once you have collected the seed pods, allow them to air dry in a cool and dry location for about two weeks. This will help reduce moisture content and prevent mold or rot during storage.

  3. Seed Storage Containers: After drying, transfer the seeds into airtight containers such as glass jars or plastic bags. It’s important to choose containers that provide a good seal to prevent moisture from entering and damaging the seeds.

  4. Labeling: Don’t forget to label your seed containers with the date of collection and the specific variety of heart plant seeds. This will help you keep track of their age and ensure you sow them within their optimal viability period.

  5. Storage Conditions: Store the labeled seed containers in a cool and dark place, such as a refrigerator or a cellar. The ideal temperature for storing heart plant seeds is around 32 to 41 degrees Fahrenheit (0 to 5 degrees Celsius). Avoid exposing the seeds to fluctuations in temperature and humidity.

By following these storage guidelines, you can extend the viability of heart plant seeds for up to a year or more.

Sowing Heart Plant Seeds

Once you are ready to sow your heart plant seeds, it’s important to choose the right time and conditions for successful germination. Here’s how to sow heart plant seeds:

  1. Timing: Heart plant seeds are best sown in late winter or early spring, as they require a period of cold stratification to break dormancy. Cold stratification mimics the natural winter conditions that these seeds would experience in their native habitats.

  2. Soil Preparation: Prepare a well-drained seed-starting mix by combining equal parts of peat moss, vermiculite, and perlite. Fill seed trays or pots with this mix and lightly tamp it down.

  3. Sowing Seeds: Sprinkle the heart plant seeds evenly over the soil surface, ensuring they are not overcrowded. As a general rule, sow the seeds at a depth equal to twice their diameter. Gently press them into the soil or cover them with a thin layer of vermiculite.

  4. Watering: Using a misting spray bottle, lightly moisten the soil until it is evenly damp but not waterlogged. Avoid overwatering, as excessive moisture can lead to fungal diseases and rot.

  5. Covering: Place a clear plastic dome or plastic wrap over the seed tray to create a mini greenhouse effect. This will help retain moisture and create a favorable environment for germination.

  6. Germination: Heart plant seeds typically take around two to four weeks to germinate. During this period, maintain a consistent temperature of around 68 to 77 degrees Fahrenheit (20 to 25 degrees Celsius) and provide indirect sunlight.

Germination and Seedling Care

Once the heart plant seeds have germinated and the seedlings start to emerge, it’s important to provide them with proper care to ensure healthy growth. Here are some tips for caring for heart plant seedlings:

  1. Light Requirements: As the seedlings grow, gradually increase their exposure to sunlight. Place them in a location with bright, indirect light for about six to eight hours a day. Avoid exposing them to direct sunlight, as it can scorch the delicate leaves.

  2. Watering: Keep the soil evenly moist but not waterlogged. Water the seedlings from below by placing the seed tray in a shallow tray filled with water. This allows the plants to absorb water as needed without risking overwatering.

  3. Transplanting: Once the seedlings have developed their first set of true leaves, they can be transplanted into individual pots or into the garden. Choose a well-drained location with partial shade for optimal growth.

  4. Fertilization: Feed the heart plant seedlings with a balanced liquid fertilizer diluted to half-strength every two weeks. This will provide them with essential nutrients for healthy growth.

By following these care guidelines, your heart plant seedlings will thrive and eventually produce their trademark heart-shaped flowers.

Conclusion

Growing heart plants from seeds can be a rewarding experience for any gardener. By properly storing, sowing, and caring for heart plant seeds, you can enjoy the beauty of these unique flowers in your own garden. Remember to be patient, as heart plants take time to establish and bloom. With proper care and attention, your heart plant seeds will grow into stunning plants that will bring joy and beauty to your outdoor space.
