Mullein Plant Seeds:
Guide to Storing, Sowing and Germination

Mullein, scientifically known as Verbascum thapsus, is a versatile and beautiful plant that is often grown for its medicinal properties and ornamental value. Native to Europe and Asia, mullein has naturalized in many parts of North America and is now widely cultivated in gardens. If you are interested in growing mullein plants in your own garden, it’s important to understand how to properly store, sow, and germinate its seeds. In this article, we will provide you with a comprehensive guide to help you successfully grow mullein from seed.

Storing Mullein Seeds

Before sowing mullein seeds, it’s crucial to ensure that they are stored properly to maintain their viability. Mullein seeds are generally small and brownish in color. Here are some steps to follow for storing mullein seeds:

1. Harvesting: Wait until the mullein flowers have finished blooming and the seed pods have turned brown before collecting the seeds. The seed pods will be dry and brittle to the touch.

2. Extraction: Gently shake or tap the seed pods over a clean container to release the small seeds. You can also use your fingers to remove the seeds from the pods.

3. Cleaning: Remove any debris or chaff from the seeds by sieving them through a fine-mesh strainer. This will ensure that only clean seeds are stored.

4. Drying: Spread the cleaned seeds on a flat surface such as a paper towel or a screen. Place them in a warm, well-ventilated area away from direct sunlight. Allow the seeds to air dry for about a week until they are completely dry.

5. Storage: Once completely dry, transfer the mullein seeds into an airtight container such as a glass jar or a plastic bag. Store the container in a cool, dark place, such as a refrigerator or a cellar, to maintain seed viability.

By following these steps, you can ensure that your mullein seeds remain viable for up to three years.

Sowing Mullein Seeds

Now that you have properly stored mullein seeds, it’s time to sow them. Mullein seeds prefer to be sown directly in the garden rather than starting them indoors. Here’s how to sow mullein seeds:

1. Soil Preparation: Choose a well-draining location in your garden that receives full sun or partial shade. The soil should be loose and fertile. Remove any weeds or debris from the area and loosen the soil with a garden fork or a tiller.

2. Sowing Time: Mullein seeds can be sown either in early spring or in late fall. If sowing in spring, wait until the soil temperature reaches around 55°F (13°C). If sowing in fall, do it at least six weeks before the first frost date.

3. Sowing Depth: Mullein seeds are tiny and require light for germination. Therefore, they should only be lightly pressed into the soil and not covered. Simply scatter the seeds on the prepared soil surface.

4. Spacing: Space the seeds about 12 inches (30 cm) apart to allow enough room for the plants to grow and spread.

5. Watering: After sowing the seeds, gently water the area using a watering can or a gentle spray from a hose. Keep the soil moist but not waterlogged throughout the germination period.

Germination of Mullein Seeds

Mullein seeds usually germinate within two to three weeks if provided with suitable conditions. Here are some tips for successful germination:

1. Temperature: Maintain a consistent temperature between 60°F (15°C) and 70°F (21°C) for optimal germination. Avoid extreme temperature fluctuations as it may hinder germination.

2. Moisture: Keep the soil consistently moist during the germination process. Avoid overwatering as it may lead to fungal diseases. A light misting of water every day should be sufficient.

3. Patience: Mullein seeds have varied germination rates, and some may take longer than others to sprout. Be patient and give the seeds enough time to germinate.

4. Thinning: Once the seedlings have emerged, thin them out to maintain a spacing of about 24 inches (61 cm) between plants. This will allow each plant to have enough space to grow and develop fully.

5. Care and Maintenance: Mullein plants are generally low maintenance once established. However, regular watering, weeding, and occasional fertilization can help promote healthy growth and abundant flowering.

By following these guidelines, you can successfully sow and germinate mullein seeds, ensuring a beautiful display of these stunning plants in your garden.

Conclusion

Growing mullein from seed can be a rewarding experience, whether you are interested in its medicinal properties or simply want to add a unique plant to your garden. By properly storing, sowing, and germinating mullein seeds, you can enjoy the beauty and benefits of these versatile plants. Remember to harvest the seeds at the right time, store them correctly, sow them directly in the garden, and provide optimal conditions for germination. With a little patience and care, you’ll soon have a flourishing mullein garden that will delight both you and nature.
