Its vibrant blooms attract pollinators, its leaves offer culinary and medicinal uses, and its lovely scent fills the air. If you’re looking to add this versatile plant to your garden, learning how to grow agastache from seed is a rewarding and cost-effective way to do so.

Choosing the Right Agastache Seeds

The first step in your agastache journey is selecting the right seeds. There are many varieties of agastache, each with its own unique characteristics. Here are some popular choices:

• Agastache foeniculum (Anise Hyssop): This classic variety is known for its strong licorice flavor and beautiful purple flowers.
• Agastache mexicana (Mexican Hyssop): With its vibrant orange blooms and citrusy fragrance, this variety is a favorite among pollinators.
• Agastache rugosa (Korean Mint): This variety boasts a spicy, minty flavor and lavender-blue flowers, making it a versatile addition to the garden.

Consider your desired flavor profile, bloom color, and growing conditions when selecting your agastache seeds.

Starting Agastache Seeds Indoors

Starting agastache seeds indoors gives them a head start and allows you to control their environment. Follow these steps for successful indoor germination:

1. Prepare the Seed Starting Mix: Choose a seed starting mix specifically designed for starting seeds indoors. This mix is lightweight and provides good drainage.
2. Fill Seed Trays or Pots: Fill your seed trays or individual pots with the seed starting mix, leaving about ½ inch of space at the top. Gently moisten the mix with water.
3. Sow the Seeds: Agastache seeds are quite small, so don’t bury them too deep. Simply sprinkle them on the surface of the soil and lightly press them down.
4. Cover with Plastic Wrap: Cover the seed tray or pot with plastic wrap to create a humid environment. This helps the seeds germinate.
5. Place in a Warm Location: Place your seed trays or pots in a warm location that receives bright, indirect light. Ideal temperatures for germination are between 70-75 degrees Fahrenheit.
6. Keep the Soil Moist: Check the soil moisture regularly and water as needed. The soil should be consistently moist but not soggy.
7. Germination: Agastache seeds usually germinate within 10-14 days. Once seedlings emerge, remove the plastic wrap and provide them with bright, indirect light.

Transplanting Agastache Seedlings Outdoors

Once your agastache seedlings have developed a few sets of true leaves, it’s time to transplant them outdoors. This typically happens 4-6 weeks after germination.

1. Harden Off Seedlings: Before transplanting, gradually acclimate your seedlings to outdoor conditions. This process, known as hardening off, reduces transplant shock. Start by placing them outdoors for a few hours each day, gradually increasing the amount of time they spend outside.
2. Prepare the Planting Site: Choose a sunny location with well-drained soil. Agastache prefers full sun but can tolerate partial shade. Amend the soil with compost or other organic matter to improve drainage and fertility.
3. Space the Seedlings: Space your agastache seedlings 12-18 inches apart. Dig a hole slightly larger than the root ball of each seedling.
4. Transplant the Seedlings: Gently remove the seedlings from their pots, being careful not to disturb the roots. Place each seedling in its designated hole, ensuring the top of the root ball is level with the soil surface. Backfill the hole with soil and gently firm it around the roots.
5. Water Thoroughly: After transplanting, water your agastache seedlings deeply. This helps them establish their roots in their new home.

Caring for Your Agastache Plants

Once your agastache is in the ground, it requires minimal care. However, a few key steps will ensure healthy growth and abundant blooms.

1. Watering: During the first few weeks after transplanting, water your agastache plants regularly to help them establish themselves. Once they are established, they are relatively drought-tolerant. Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
2. Fertilizing: Agastache plants are light feeders. You can fertilize them once or twice during the growing season with a balanced fertilizer.
3. Deadheading: To encourage continuous flowering, deadhead spent blooms. This involves removing the faded flower heads.
4. Winter Protection: Depending on your climate, agastache may die back in the winter. In colder regions, you can protect your plants by mulching around the base with a thick layer of organic matter.

Harvesting Agastache Leaves and Flowers

Agastache leaves and flowers are both edible and fragrant, adding a unique touch to culinary creations.

1. Harvesting Leaves: The best time to harvest agastache leaves is before the plant flowers. The leaves have the strongest flavor at this stage. Harvest leaves as needed by simply pinching them off the stems.
2. Harvesting Flowers: Harvest agastache flowers when they are fully open and vibrant. Use them fresh in salads, desserts, or teas, or dry them for later use.

Enjoying the Beauty and Flavor of Your Agastache

Agastache plants are a joy to behold, attracting hummingbirds, butterflies, and other beneficial insects to your garden. Their aromatic leaves and flowers add a unique touch to culinary creations, while their beautiful blooms bring a touch of elegance to your landscape.

Beyond the Garden: Culinary and Medicinal Uses

Agastache has been used for centuries for its culinary and medicinal properties.

• Culinary Uses: Agastache leaves and flowers can be used to flavor teas, soups, sauces, and desserts. They also make a delicious addition to salads and salsas.
• Medicinal Uses: Agastache has been traditionally used to treat digestive issues, respiratory problems, and skin conditions. However, it’s important to consult with a healthcare professional before using agastache for medicinal purposes.
