Agastache rugosa (Korean Mint)

Seed Treatment (Stratification)

  • Seeds can benefit from a brief period of chilling. Place seeds in a damp paper towel inside a plastic bag and refrigerate for 1-2 weeks before planting.

How to Plant:

  1. Sowing Time: Start indoors 6-8 weeks before the last frost or direct sow in spring after the danger of frost has passed.

  2. Soil Requirements: Prefers well-draining, sandy, or loamy soil with a pH of 6.0-7.5.

  3. Light Requirements: Needs full sun for best growth and flowering.

  4. Seed Depth: Lightly press seeds into the soil—do not cover as they require light to germinate.

  5. Watering: Keep the soil evenly moist but not waterlogged until germination occurs.

  6. Germination Time:7-14 days at temperatures of 65-75°F (18-24°C).

  7. Spacing: Thin seedlings to 12-18 inches (30-45 cm) apart once established.

Additional Tips:

  • Drought-tolerant once established but grows best with regular watering.

  • Attracts pollinators like bees, butterflies, and hummingbirds!

  • Can be grown in containers, herb gardens, or flower beds.

  • Leaves are fragrant and edible, often used in teas or garnishes.
