If you’re looking for a native plant that combines stunning blooms, incredible drought tolerance, and pollinator appeal, let me introduce you to Trans-Pecos giant hyssop (Agastache breviflora). This delightful member of the mint family proves that desert plants can be both beautiful and practical in the garden.
What Makes This Plant Special?
Trans-Pecos giant hyssop is a true southwestern native, calling Arizona and New Mexico home. As a perennial forb, it lacks the woody stems of shrubs but returns year after year with reliable blooms and aromatic foliage. Don’t let the giant in its name fool you – this plant earns its title through the impact of its flower displays rather than overwhelming size.
This native beauty grows naturally in Arizona and New Mexico, where it has adapted perfectly to the challenging desert conditions. Its natural range speaks to its incredible resilience and ability to thrive where many other plants struggle.

The real magic happens when Trans-Pecos giant hyssop bursts into bloom with dense spikes of small, tubular flowers in lovely shades of lavender to purple. These blooms create a stunning vertical accent in the garden while releasing a pleasant, minty fragrance when you brush against the foliage.
This plant shines brightest in:
