Updated: May 8, 2024

Coleus plants are well-loved for their vibrant foliage and easy care requirements. Among the various cultivars available, the Black Dragon Coleus stands out for its striking dark leaves with hints of bright green. Growing these plants from seeds can be a rewarding experience, allowing you to witness the entire life cycle of these beautiful plants. In this guide, we will explore the best practices for storing, sowing, and germinating Black Dragon Coleus plant seeds to ensure successful growth.

Storing Coleus Seeds

Proper storage of coleus seeds is essential to maintain their viability for future planting seasons. Follow these steps to ensure your Black Dragon Coleus seeds stay healthy and ready for sowing:

  1. Harvesting Seeds: Wait for the seed pods on your mature Black Dragon Coleus plants to dry out completely before collecting the seeds. The pods should turn brown and start to crack open naturally.

  2. Seed Extraction: Once the seed pods are dry, gently remove them from the plant and carefully extract the small, dark coleus seeds from inside. Use a pair of tweezers or your fingers to separate the seeds from the pods.

  3. Cleaning Seeds: To remove any remaining debris or chaff, place the extracted coleus seeds on a clean paper towel or cloth and gently blow over them. This will help clean the seeds without damaging them.

  4. Storage Container: Transfer the cleaned seeds into a small paper envelope or airtight container labeled with the plant variety and date of collection. Store the container in a cool, dry place away from direct sunlight.

  5. Temperature Control: Ideally, coleus seeds should be stored at a consistent temperature between 40-50°F (4-10°C). Avoid exposure to extreme heat or humidity, as this can reduce seed viability.

By following these steps, you can preserve your Black Dragon Coleus seeds for future use and ensure a higher germination rate when it’s time to sow them.

Sowing Coleus Seeds

Now that you have properly stored your Black Dragon Coleus seeds, it’s time to sow them and kickstart the germination process. Here’s how you can sow your coleus seeds effectively:

  1. Seed Starting Mix: Fill a small seed tray or pots with a well-draining seed starting mix. You can also create your own mix by combining equal parts peat moss, perlite, and vermiculite.

  2. Moistening the Soil: Before sowing the seeds, moisten the seed starting mix evenly with water. Ensure that the soil is damp but not waterlogged to prevent rotting of the seeds.

  3. Sowing Seeds: Gently scatter the Black Dragon Coleus seeds evenly on top of the soil surface. Lightly press the seeds into the soil, but do not bury them too deep as coleus seeds require light for germination.

  4. Covering Seeds: To retain moisture and humidity, cover the seed tray or pots with a clear plastic dome or plastic wrap. Place the covered container in a warm location with indirect sunlight.

  5. Misting: Check the soil moisture regularly and mist lightly if it starts to dry out. Avoid overwatering as it can lead to fungal diseases.

By following these steps, you can create an ideal environment for your Black Dragon Coleus seeds to begin germinating successfully.

Germinating Coleus Seeds

Germination is an exciting stage in the life cycle of plants where tiny seedlings emerge from their dormant state and start growing. Here are some tips to help facilitate germination of your Black Dragon Coleus seeds:

  1. Warmth: Coleus seeds prefer warm temperatures for germination, around 70-75°F (21-24°C). Consider using a seedling heat mat to provide consistent warmth to promote germination.

  2. Light: As mentioned earlier, coleus seeds require light for germination. Ensure that they are placed in a bright location with indirect sunlight to encourage healthy growth.

  3. Patience: Germination times can vary depending on conditions, but you should start seeing seedlings emerge within 1-2 weeks after sowing. Be patient and continue providing the necessary care during this stage.

  4. Transplanting: Once your Black Dragon Coleus seedlings have developed several sets of true leaves, they can be transplanted into individual pots with well-draining soil. Gradually acclimate them to outdoor conditions before planting them in their final garden spot.

  5. Maintenance: Regularly water and fertilize your coleus plants as they grow to ensure healthy foliage development. Keep an eye out for pests or diseases and address them promptly.

By following these guidelines for storing, sowing, and germinating Black Dragon Coleus plant seeds, you can enjoy growing these stunning plants in your garden or indoor space. With patience and proper care, you’ll soon be rewarded with lush foliage that adds a unique touch to your green space.


In conclusion, growing Black Dragon Coleus plants from seeds is a fulfilling experience that allows you to witness the entire growth cycle of these captivating plants. By following proper storage techniques, sowing practices, and germination tips outlined in this guide, you can increase your chances of successfully cultivating healthy Black Dragon Coleus plants from seed.
