Agastache rupestris (Sunset Hyssop) is an upright perennial boasting showy spikes of tubular salmon-orange flowers with purplish calyxes from early to late summer. Eye-popping, they are borne above the foliage of silvery-green, narrow leaves. Providing an outstanding garden performance, Agastache rupestris adds color as well as a lovely spiky texture to the garden.

  • Grows up to 18-30 in. tall (45-75 cm).
  • Easily grown in full sun, in average, dry to medium moisture, well-drained soils. Dislikes damp conditions and needs excellent drainage. Although a drought-tolerant plant, it might need watering in extreme dry weather spells.
  • Provides a bold visual impact in beds and borders, cottage gardens, city gardens, or butterfly gardens over a very long season. Great as cut flowers too!
  • Ideal to add color to the late-season garden when many other plants are fading.
  • Creates a stunning effect when mixed with other perennials or planted en masse.
  • Attracts streams of hummingbirds, butterflies, and other beneficial pollinators.
  • Generally disease and pest-free (might occasionally be subject to powdery mildew) and resistant to deer and rabbits.
  • Remove spent flowering spikes through the season.
  • Propagate by seed.
  • Native to Arizona, New Mexico.
