Safety Overview
1.Agastache Rugosa — Overview
Agastache rugosa, commonly known as Korean Mint or Wrinkled Giant Hyssop, is a distinguished herbaceous perennial belonging to the Lamiaceae family. Native to East Asia, particularly Korea, China, and Japan, this aromatic plant is characterized by its upright, bushy growth habit, typically reaching heights of 60 to 120 cm. Its stems are square, a hallmark feature of the mint family, and are often flushed with purplish hues. The leaves are opposite, ovate-lanceolate, with serrated margins, and emit a strong, pleasant minty-anise scent when crushed.
They grow to about 5-10 cm in length, tapering to a pointed apex. From mid-summer to early autumn, Agastache rugosa produces dense, terminal spikes of small, tubular flowers, which can vary in color from lavender-blue to violet-purple, and occasionally white. These inflorescences are highly attractive to a wide array of pollinators, including bees and butterflies, making the plant a valuable addition to ecological gardens. Agastache rugosa thrives in full sun to partial shade and prefers well-drained, moderately fertile soil.
It exhibits good drought tolerance once established but benefits from consistent moisture. Its natural habitat includes open fields, forest edges, and disturbed areas, where it can form impressive colonies. Beyond its ornamental and ecological value, Agastache rugosa is deeply rooted in traditional East Asian medicinal practices, revered for its multifaceted therapeutic properties.
