Variety description

10 August 2026

A perennial herbaceous plant reaching a height of 60–90 cm. The variety is a complex hybrid derived from crossing Agastache cusickii, A. cana, and A. pallida. The foliage is aromatic, emitting a mint-licorice scent when crushed, and may acquire a bronze or dark hue in cool weather.

The plant flowers from late spring to early autumn. It is characterized by winter hardiness in zones 5–10 and good resistance to powdery mildew. Excessive soil fertilization may lead to lodging of the stems. The variety is used for flower beds, borders, and container gardening, attracting pollinators.
