Agastache pallidiflora, commonly known as New Mexico Giant Hyssop, is a semi-deciduous perennial herb native to the Southwestern United States and Mexico, particularly found in meadows, open areas, and along streams. It typically grows to a height of 3-4 feet (0.9-1.2 meters) and a width of 0.7-1 feet (0.2-0.3 meters). This plant features a spiky form with showy, tubular purple flowers that bloom in the summer, attracting pollinators such as hummingbirds and butterflies.

New Mexico Giant Hyssop is valued for its aromatic foliage and vibrant flowers, making it a popular choice for sensory gardens, borders, and naturalistic plantings. It is drought-tolerant once established, requiring minimal maintenance, which adds to its appeal for xeriscaping. While it thrives in full sun, it can also tolerate partial shade. It prefers well-drained soils and can be susceptible to root rot if overwatered. There are no significant disease problems, but powdery mildew can occur in humid conditions.CC BY-SA 4.0
