ABOUT

Agastache foeniculum, commonly known as Anise Hyssop, is a perennial herb that is well-known for its appealing visual characteristics and aromatic properties. The plant has a bushy clump-forming habit and features upright branching stems. The foliage of Anise Hyssop is comprised of ovate to lance-shaped leaves that are bright green and have a slightly wrinkled texture with serrated edges. When crushed, these leaves release a pleasant anise or licorice-like fragrance. The visual highlight of Anise Hyssop is its stunning flower spikes that bloom in the warmer months. The flowers are small, tubular shaped, and densely arranged on terminal spikes. They are a rich lavender-blue color, which adds a striking display of color to garden settings. These attractive flowers are not only a feast for the eyes but also attract a variety of pollinators, including bees, butterflies, and hummingbirds. Complementing the vibrant flowers, the stems and foliage sometimes take on a purplish hue, which adds further interest and contrast to the plant's appearance. As the seasons progress into late summer and autumn, the flowers may give way to small dry fruit, which can persist into the winter, providing textural interest in the landscape even as other plants die back. The overall appearance of Anise Hyssop—with its combination of fragrant foliage, striking blue flowers, and attractive form—makes it a popular choice for ornamental gardens, herb gardens, and as a border plant, where it contributes both aesthetic beauty and aromatic foliage.

Pruning
  • water dropWater

    The anise hyssop should be watered deeply once a week, providing about 1 inch of water each time to soak the soil thoroughly. During periods of extreme heat or drought, extra water may be needed, so observing your plant's response to the weather is crucial. Containers may require more frequent watering, possibly every few days, due to quicker drying of the soil. As a drought-tolerant plant once established, anise hyssop is more tolerant of dry conditions than overwatering. Be cautious not to overwater, as this can lead to root rot.

  • sunLight

    Anise hyssop thrives in full sun of at least 6 hours per day but can tolerate partial shade. For best growth and flowering, position the plant in a spot where it receives abundant sunlight, as too much shade can lead to sparse blooms and a leggy plant.

  • thermometerTemperature

    Anise hyssop can survive in a temperature range between 50°F and 90°F; however, it prefers the warmer end of this spectrum. Frost can damage the plant, so it's best to ensure the temperature stays above the minimum. The ideal growing conditions are within 60°F to 70°F.

  • scissorsPruning

    Pruning anise hyssop can promote bushier growth and prevent the plant from becoming too leggy. Deadheading or removing the spent blooms can encourage a second flowering in the season. Prune the plant in early spring or after the first flush of blooms fades, typically in the midsummer. Annual or biennial trimming to shape the plant is usually sufficient.

  • broomCleaning

    As needed

  • bambooSoil

    Anise Hyssop (Agastache foeniculum) thrives in well-draining soil amended with compost or other organic matter. A soil pH ranging from 6.0 to 8.0 is optimal for its growth. It is drought tolerant, so a mix that doesn't retain excessive moisture is best, such as a blend of two parts garden soil, one part perlite or coarse sand, and one part compost.

  • plantRepotting

    Anise Hyssop should be repotted every 2-3 years to refresh the soil and provide room for growth. The best time to repot is in the spring, just before the growing season begins, ensuring the plant can quickly establish in its new container.

  • water dropsHumidity & Misting

    Anise Hyssop prefers moderate humidity levels but is quite adaptable and can tolerate both low and high humidity. It will not require specific humidity adjustments when grown in normal household environments.

  • circleLife cycle

    Agastache foeniculum, commonly known as Anise Hyssop, begins its life cycle as a seed, typically sown in the spring after the threat of frost has passed. Upon germination, the seedling emerges and develops into a small rosette of leaves at the soil surface. As it matures, Anise Hyssop produces a sturdy stem that can reach up to 3 feet tall, along with opposite pairs of ovate leaves with a distinct anise scent when crushed. The vegetative stage transitions to the reproductive phase in midsummer, when it forms spiky, purple flower inflorescences that attract various pollinators such as bees and butterflies. After pollination, the flowers produce small nutlets as fruits, which contain the seeds for the next generation. The plant completes its cycle by senescing in late fall, though it can re-emerge from its root system or self-seed the following year if conditions are favorable.

      Spring to summer

    • The most popular method of propagating Agastache foeniculum, commonly known as anise hyssop, is by seed. To propagate anise hyssop by seed, one should ideally sow seeds in late winter or early spring. The process involves lightly pressing the seeds into a seed-starting mix, as they require light for germination. The soil should be kept moist but not waterlogged, with temperatures around 70 degrees Fahrenheit (21 degrees Celsius). Seedlings will typically emerge in 7 to 14 days. Once they have grown and the danger of frost has passed, the young plants can be transplanted outdoors to a sunny spot with well-drained soil. It's important to space the plants about 12 to 18 inches (30 to 45 centimeters) apart to allow for adequate air circulation and growth.
