Similar to Salvias, the Agastache genus is a member of the mint family (Lamiaceae) and flowers in a broad range of colors including blues, oranges, reds, pinks, purples and yellows. As with so many mint family members, Agastaches are pleasantly aromatic and long blooming.

Agastaches are full-sun plants with floriferous plumes of tiny, tubular flowers and foliage that ranges from tiny, needle-like leaves to large, fleshy basal rosettes. Species from the Southwest and Mexico are particularly tolerant of heat and drought. In general, these plants grow better in low fertility soils; give them too much nitrogen and they become floppy. (Propagation by seed also tends to produce lax form.) Similar to Salvias, they need soil with good drainage.

Agastache flowers are magnets for butterflies, honeybees and hummingbirds. The allure for pollinators is even stronger when these plants are mixed with nectar-rich Salvias (sages). Deer tend to avoid plants from both genuses.

It's estimated that 22 to 30 species of Agastache exist worldwide, of which 21 are native to North America with most originating in the Southwest. One extremely cold-hardy species, Agastache rugosa, comes from Asia. It is commonly known as Anise Hyssop or Korean Mint.

At Flowers by the Sea, we prefer growing compact varieties of Agastaches, including the tough, lovely hybrids that result when Southwestern species are crossed with varieties of A. rugosa. These hybrids adapt to a broad range of USDA Cold Hardiness Zones and, although drought tolerant, can handle more moisture than Southwestern species.

Many Agastaches have a heady aroma that has been described as being a combination of anise (a licorice-like scent), citrus and mint. Some have a more pungent smell similar to tarragon. Agastache essential oils are complex combinations of chemicals and are valued for their use in flavorings, perfumes and pharmaceuticals.

We value the genus for its beauty, fragrance, nectar-rich flowers, ease of growth, low-water demands and compatibility with sages.


  • Agastache 'Blue Boa'

    (Blue Boa Hummingbird Mint) Luxurious deep violet-blue flower spikes held over ultra-green foliage. Unlike any other Agastache varieties, the flower spikes are long, wide and extremely showy.


  • Agastache cana 'Sinning'

    (Sonoran Sunset® Anise Hyssop) An abundance of lavender-rose flowers mark Agastache cana 'Sinning' as being unique from the typical purple-flowered plants of its species. Colorado plantsman Duane Sinning discovered this lovely hybrid.


  • Agastache x 'Ava'

    (Ava Hybrid Anise Hyssop) Raspberry calyxes support Ava's rosy-pink flowers, which whorl on tall spikes similar to many Salvias. When the blossoms are spent, the calyxes remain colorful. This long-blooming hummingbird magnet is tolerant of cold, heat and drought.


  • Agastache x 'Kudos Coral'

    (Kudos Coral Hybrid Anise Hyssop) Dense plumes of deep coral flowers are accented by mid-green foliage in this heat- and drought-tolerant favorite of pollinators. Kudos Coral is a compact, clumping, semi-dwarf variety.


  • Agastache x 'Kudos Mandarin'

    (Kudos Mandarin Hybrid Anise Hyssop) Dense plumes of creamy orange flowers are accented by deep green foliage in this heat- and drought-tolerant favorite of pollinators. Kudos Mandarin is a compact, clumping, semi-dwarf variety.


  • Agastache x 'Kudos Yellow'

    (Kudos Yellow Hybrid Anise Hyssop) Flowers by the Sea is one of the first nurseries nationwide to grow Agastache x 'Kudos Yellow'. This is one of the best deep yellow Agastaches we've found, due to its large, dense flower spikes and bushy, upright form.

Plant is doing well but not yet the showy plant described. Providing great late summer color and survived a week of 100+ temps without any attention.
