Agastache Foeniculum 100 Seeds – Anise Hyssop Licorice Mint Blue Giant Hyssop Pollinator Herb

Agastache foeniculum, commonly known as anise hyssop, licorice mint, or blue giant hyssop, is a hardy perennial herb prized for its fragrant foliage and long-lasting lavender-blue flower spikes. The leaves release a sweet anise or licorice scent when brushed or crushed, making this plant a delightful addition to herb gardens, perennial borders, and pollinator-friendly landscapes. Its tall, upright flower spikes bloom through summer and into early fall, attracting bees, butterflies, and hummingbirds.

Anise hyssop is easy to grow from seed and offers multiple uses in the garden. The aromatic leaves can be used fresh or dried for teas and culinary creations, while the striking flowers add vertical interest and a soft blue-purple hue to mixed plantings. It pairs well with other drought-tolerant perennials and works beautifully in cottage gardens, meadow plantings, and wildlife gardens.

Planting & Care

Sow anise hyssop seeds indoors 6-8 weeks before the last frost or directly in the garden after the danger of frost has passed. Press seeds lightly into the soil surface; they need light to germinate. Keep the soil consistently moist but not waterlogged. Germination typically occurs in 10-20 days at temperatures around 65-70°F. Once seedlings have several sets of true leaves, transplant them outdoors after hardening off.

Anise hyssop thrives in full sun and well-drained soil. Water regularly during the first growing season to help plants establish, then reduce watering as they become drought-tolerant. Deadhead spent flowers to encourage continued blooming, or leave seed heads for winter interest and self-seeding. Divide clumps every few years to maintain vigor.
