Anise Hyssop
Astello Indigo Agastache is a compact, ornamental herb that brings deep indigo blooms and fresh minty fragrance to any garden space. Originally introduced by Dutch seed company Van Hemert and Co, this vigorous grower reaches just 20 inches tall while maintaining a neat, tidy clump habit. It's an edible ornamental that serves double duty as a pollinator magnet, drawing butterflies and beneficial insects throughout summer and fall with its soothing, calming color and abundant nectar.

What sets Astello Indigo apart is its rare combination of ornamental beauty and practical utility. The glorious dark green foliage and striking indigo blooms create a genuinely striking garden presence, while its minty fragrance adds sensory appeal and hints at its culinary potential. Its compact, vigorous growth habit and season-long nectar production make it equally valuable to the aesthetic gardener and the pollinator advocate. This is an herb that doesn't hide itself away in a corner, it commands attention while quietly feeding your garden's ecosystem.
As an edible ornamental, Astello Indigo works beautifully in garden spaces where visual appeal matters as much as function. The minty fragrance and edible flowers make it suited to tea preparations, garnishes, and culinary infusions that celebrate both the plant's aroma and visual character.
Harvest indigo flowers and foliage as needed once the plant is established. Flowers are best gathered in the morning after dew dries. For minty foliage, pinch leaves and stems throughout the growing season. The plant's continuous flowering from summer through fall means you can harvest regularly without depleting the plant.
The compact growth habit of Astello Indigo means minimal pruning is required, but deadheading spent flowers encourages continuous blooming throughout summer and fall. Light shaping in early summer helps maintain the neat clump form and prevents the plant from becoming leggy.
