Lemon Verbena Plant Seeds:
Guide to Storing, Sowing and Germination

Lemon verbena (Aloysia citrodora) is a popular herb known for its fragrant leaves and citrusy aroma. It is commonly used in teas, desserts, and even cocktails. If you are a fan of this flavorful herb, you might be interested in growing your own lemon verbena plants from seeds. In this article, we will guide you through the process of storing, sowing, and germinating lemon verbena plant seeds.

Storing Lemon Verbena Seeds

Before you can sow lemon verbena seeds, it is important to properly store them to ensure their viability. Here are some steps to follow:

1. Harvesting: Wait until the lemon verbena plant has produced seed heads. These seed heads will contain the seeds you can collect. Allow the seed heads to dry on the plant for a few weeks until they turn brown and begin to crack open.

2. Seed Extraction: Once the seed heads have dried, gently shake or rub them to release the seeds. Collect the seeds in a clean container such as a small jar or envelope.

3. Cleaning: Lemon verbena seeds are tiny and can easily get mixed with debris or chaff. To clean them, use a fine-mesh sieve or strainer to separate the seeds from any unwanted material.

4. Drying: After cleaning, spread the seeds on a paper towel or a plate in a single layer. Allow them to air dry for about a week or until they are completely dry. Make sure they are stored in a cool and dry location during this time.

5. Storage Containers: Once the seeds are fully dry, transfer them to an airtight container such as a ziplock bag or a glass jar with a tight-fitting lid. Label the container with the date of collection and the variety of lemon verbena, if known.

6. Storage Conditions: To maintain seed viability, store the container in a cool, dark, and dry place. A refrigerator or a basement are ideal locations for long-term seed storage.

By following these steps, you can ensure that your lemon verbena seeds are properly stored and ready for sowing when the time comes.

Sowing Lemon Verbena Seeds

Now that you have properly stored your lemon verbena seeds, it’s time to sow them. Here’s how you can do it:

1. Timing: Lemon verbena seeds can be sown either indoors or outdoors, depending on your climate and growing conditions. In most regions, it is best to start the seeds indoors about 8-10 weeks before the last frost date.

2. Seed Trays/Pots: Fill a seed tray or small pots with a well-draining potting mix. Moisten the soil lightly before sowing the seeds.

3. Sowing Depth: Lemon verbena seeds are tiny and should be sown shallowly. Scatter the seeds on the soil surface and gently press them down with your fingers. Avoid burying them too deep.

4. Covering: After sowing, cover the seeds lightly with a thin layer of vermiculite or fine sand. This will help maintain moisture around the seeds and improve germination rates.

5. Watering: Water the seeds gently using a misting spray bottle or a watering can with a fine rose attachment. Keep the soil consistently moist but not waterlogged throughout the germination process.

6. Temperature and Light: Lemon verbena seeds require warmth and light to germinate. Place the seed tray or pots in a warm location with temperatures around 70-75°F (21-24°C). Provide bright indirect light or use grow lights to ensure adequate lighting.

7. Germination Time: Lemon verbena seeds typically take around 2-3 weeks to germinate. Keep an eye on the seedlings and make sure to maintain proper moisture levels during this period.

Germination and Care of Lemon Verbena Seedlings

Once the lemon verbena seeds have germinated, it’s important to provide proper care to ensure their healthy growth. Here are some tips:

1. Thinning: If multiple seedlings emerge from one spot, gently thin them out to allow adequate space for each plant to grow. This will prevent overcrowding and competition for resources.

2. Transplanting: When the seedlings have grown a few sets of true leaves and are large enough to handle, you can transplant them into individual pots or containers. Use a well-draining potting mix and provide ample space for root development.

3. Watering: As the seedlings grow, water them regularly but avoid overwatering. Allow the top inch of soil to dry out between waterings to prevent root rot.

4. Light and Temperature: Place the seedlings in a location that receives at least 6 hours of direct sunlight or provide supplemental grow lights. Maintain temperatures between 60-75°F (15-24°C) during the day and slightly cooler at night.

5. Fertilizing: Once the seedlings have established themselves in their new pots, you can begin fertilizing them with a balanced liquid fertilizer diluted according to package instructions. Apply the fertilizer every 2-3 weeks during the growing season.

6. Hardening Off: Before permanently placing your lemon verbena plants outdoors, gradually acclimate them to outdoor conditions through a process called hardening off. Start by placing them outdoors for a few hours each day, gradually increasing their exposure over a week or two.

By following these guidelines for germination and care, you can successfully grow lemon verbena plants from seeds and enjoy their delightful aroma and flavor in your culinary endeavors.

In conclusion, growing lemon verbena plants from seeds can be a rewarding experience for any herb enthusiast. By properly storing, sowing, and caring for the seeds, you can successfully cultivate your own lemon verbena plants and enjoy their aromatic leaves for years to come. So why not give it a try and add this versatile herb to your garden?
