Pringle’s Giant Hyssop

Agastache pringlei var. verticillata, commonly known as Pringle’s Giant Hyssop, is a perennial herbaceous plant native to the southwestern United States and northern Mexico, particularly thriving in regions such as Arizona and New Mexico. This variety typically exhibits a robust growth habit, reaching heights of 1 to 3 feet (30 to 90 cm) and forming a clumping or bushy structure. The stems are often square in cross-section, a characteristic feature of the Lamiaceae family, to which this species belongs.

The leaves of Pringle’s Giant Hyssop are lanceolate to ovate, measuring 2 to 4 inches (5 to 10 cm) in length, and are arranged oppositely along the stem. They are typically aromatic when crushed, releasing a minty scent. The flowers, which bloom from late summer to early fall, are tubular and can vary in color from lavender to deep purple, attracting a variety of pollinators, including bees and hummingbirds. The inflorescences are arranged in whorls, which contribute to the plant’s ornamental appeal. Following the flowering period, the plant produces small, nutlet-like fruits that are dispersed by wind and animals.

Ecologically, Agastache pringlei var. verticillata plays a significant role in supporting local pollinator populations, thus contributing to the overall health of its ecosystem. The plant is also utilized in traditional herbal medicine for its potential therapeutic properties, including its use as a digestive aid and for respiratory issues. An interesting adaptation of this species is its drought tolerance, allowing it to thrive in arid conditions by developing a deep root system that accesses moisture from deeper soil layers. This resilience makes it a valuable addition to xeriscapes and low-water gardens.
