This easy-to-grow perennial herb shares some similarities with mint, including its aromatic foliage. Native to the Southern United States, Agastache cana derives its name from the Latin word “cana,” meaning grey, which refers to the plant’s greyish-green leaves.
Characteristics and Description

When the leaves of Agastache cana are crushed, they emit a refreshing minty fragrance. From late spring through summer and into fall, this perennial produces bright pink flowers, which contribute vibrant color to the garden for an extended period.
The flowers of Agastache cana are tubular and grow on tall spikes. Each flower consists of five petals fused together, forming the characteristic tube shape.

Cultivation of Agastache cana:
Agastache cana is a resilient plant that thrives in various growing conditions. Here are some key factors to consider when cultivating this perennial:
Sunlight: Agastache cana flourishes in full sun or partial shade. However, providing ample sunlight will promote more abundant flowering and enhance the plant’s overall vigor.
Watering: During the first year after planting, regular watering is essential to establish Agastache cana. Once established, this plant is remarkably drought-tolerant and requires watering only during extended dry periods.
