Agastache rugosa 'Liquorice Blue' – The fragrant anise plant full of color and bee life

Agastache rugosa 'Liquorice Blue', also known as licorice plant or Korean mint, is a versatile, fragrant perennial that not only adorns gardens with its beautiful flowers but also attracts bees, bumblebees, and butterflies. This plant combines vigorous growth with a long blooming period and a delightful anise-like fragrance – a true favorite for lovers of fragrant, low-maintenance gardens.

Origin and characteristics of Agastache rugosa

The Agastache rugosa is native to East Asia, where it grows on sunny slopes and open fields. The cultivar 'Liquorice Blue' is an elegant variety distinguished by its striking lavender-blue flowers and dark green, fragrant leaves. The plant belongs to the Lamiaceae family, which also includes mint, sage, and lavender.

The anise plant grows to an average height of 60 to 90 cm and forms sturdy, upright stems. In summer, from July to October, it blooms profusely with dense clusters of small, blue-purple flowers. These flowers exude a subtle anise scent that not only appeals to humans but also exerts an irresistible attraction on bees, bumblebees, and butterflies—ideal for a bee-friendly garden.

Location and care

The Agastache rugosa 'Liquorice Blue' thrives in a sunny, warm spot with well-drained soil. While the plant tolerates drought well once established, it doesn't like wet feet. A chalky, moderately fertile soil is ideal.

In winter, the plant can freeze slightly during a hard frost, but it usually sprouts again in spring. For extra protection, a layer of mulch or leaves during the winter can be helpful. Don't cut back spent flower stems until early spring, so the plant can protect itself from the cold and also provide birds with food in the form of seeds.

Care tips:

• Provide water during prolonged drought.

• Remove spent flowers to encourage further flowering.

• Use Agastache as a cut flower or for fragrant bouquets.

• Planting distance: approximately 30–40 cm.

Combinations and applications in the garden

'Liquorice Blue' is a real eye-catcher in the border. Its blue hues combine beautifully with coneflower (Echinacea), catnip (Nepeta), sage (Salvia), and ornamental grasses. In herb gardens, it thrives among lavender and thyme, adding height, fragrance, and color variation.

Agastache is also an excellent choice for pots or containers—provided there's good drainage. The plant fits into natural, Mediterranean, or prairie-like plantings, where it blends harmoniously with other drought-tolerant species.

Edible and fragrant

A nice bonus of Agastache rugosa 'Liquorice Blue' is that the leaves are edible. They have a subtle licorice or anise flavor and can be used in tea, salads, or desserts. The flowers are also edible and make a colorful garnish.

The fragrant leaves can be dried and added to potpourri or herbal blends. This way, you can enjoy this versatile plant not only in the garden but also indoors.
