Hummingbird Mint Plant Seeds:
Guide to Storing, Sowing and Germination

Hummingbird mint, also known as agastache or hyssop, is a popular plant for attracting hummingbirds and other pollinators to your garden. With its vibrant flowers and aromatic foliage, it’s no wonder that many gardeners are eager to grow this beautiful and beneficial plant.

If you’re interested in growing hummingbird mint from seeds, it’s important to know how to properly store, sow, and germinate them. In this article, we will provide a comprehensive guide to help you successfully grow hummingbird mint from seed.

Storing Hummingbird Mint Seeds

Before we dive into the details of sowing and germination, let’s talk about storing hummingbird mint seeds. Proper seed storage is crucial to maintain seed viability and ensure successful germination in the future.

1. Seed Collection: The first step in storing hummingbird mint seeds is collecting them. Wait until the flowers have faded and the seed heads have turned brown before harvesting. Cut the seed heads off the plant and place them in a paper bag or envelope.

2. Drying: Once you have collected the seed heads, allow them to dry in a well-ventilated area for about a week. This will ensure that the seeds are fully mature and ready for storage.

3. Cleaning: After drying, gently rub the seed heads between your hands or use a sieve to separate the seeds from any debris or chaff.

4. Storage Container: Transfer the cleaned seeds to an airtight container such as a glass jar or a plastic bag with a zip-lock seal. Make sure to label the container with the date of collection and the plant’s name.

5. Ideal Conditions: Store the container in a cool, dry place away from direct sunlight. A refrigerator or a basement can be suitable locations for long-term storage.

By following these steps, you can store hummingbird mint seeds for up to 2 years while maintaining their viability.

Sowing Hummingbird Mint Seeds

Now that you have properly stored hummingbird mint seeds, it’s time to sow them. Here’s how to go about it:

1. Timing: The best time to sow hummingbird mint seeds is in early spring, after the danger of frost has passed. Alternatively, you can sow them indoors 6-8 weeks before the last expected frost date.

2. Seed Starting Mix: Fill seed trays or pots with a well-draining seed starting mix. Avoid using regular potting soil, as it can become too compacted and hinder proper root development.

3. Moisture: Moisten the seed starting mix before sowing the seeds. It should be evenly moist but not soaking wet. Excess moisture can lead to rot and fungal diseases.

4. Sowing: Sprinkle the seeds on the surface of the seed starting mix, making sure they are evenly spaced. Lightly press them into the soil or cover them with a thin layer of vermiculite or fine sand.

5. Covering: Place a clear plastic dome or a plastic wrap over the seed trays or pots to create a mini greenhouse effect. This helps retain moisture and create optimal conditions for germination.

6. Temperature and Light: Keep the seeds at a temperature of around 70°F (21°C) for optimal germination. Additionally, provide bright indirect light to encourage healthy growth.

7. Watering: Water the seeds gently from the bottom by placing the trays or pots in a shallow tray filled with water. This ensures that the seeds receive moisture without disturbing them.

8. Germination Period: Hummingbird mint seeds typically germinate within 10-21 days, although it can vary depending on environmental conditions and seed freshness.

Germination and Care

Once the seeds have germinated, it’s important to provide proper care to ensure the healthy growth of your hummingbird mint plants:

1. Transplanting: When the seedlings have developed their second set of true leaves, they are ready to be transplanted into individual pots or into the garden. Be gentle when handling the delicate roots.

2. Growing Conditions: Hummingbird mint thrives in full sun and well-draining soil. Choose a location in your garden that receives at least 6-8 hours of sunlight per day.

3. Watering: Keep the soil consistently moist but not waterlogged. Water deeply whenever the top inch of soil feels dry. Avoid overhead watering, as it can lead to fungal diseases.

4. Fertilization: Apply a balanced fertilizer every 4-6 weeks during the growing season to provide essential nutrients for healthy plant growth.

5. Pruning: Regularly trim back the spent flowers to encourage continuous blooming and prevent the plant from becoming leggy.

6. Overwintering: In colder climates, hummingbird mint plants may not survive the winter. Consider bringing them indoors or providing winter protection by mulching around the base of the plant.

By following these guidelines, you can successfully grow hummingbird mint from seed and enjoy its beautiful blooms and the delightful presence of hummingbirds in your garden.

In conclusion, growing hummingbird mint from seeds is a rewarding endeavor that allows you to attract pollinators and enhance your garden’s beauty. By properly storing, sowing, and germinating the seeds, you can ensure successful growth and enjoy this vibrant plant for years to come.
