  • Naturalized meadow areas with plenty of space
  • Drought-tolerant landscapes and xeriscapes
  • Wildlife habitat gardens
  • Large-scale restoration projects

Growing Conditions and Care

This mountain native has some specific preferences, but once you understand them, it’s relatively low-maintenance:

Climate: Best suited for USDA hardiness zones 8-10, particularly areas with Mediterranean climates similar to its native California range.

Sun and Soil: Give it full sun and well-draining soil. It’s not picky about soil type but absolutely cannot tolerate soggy conditions.

Water: Here’s the best part for California gardeners – once established, Hall’s mule-ears is very drought-tolerant. Water regularly during its first growing season, then back off and let nature take over.

Planting and Care Tips

  • Start from seed in fall or early spring, or purchase small plants from native plant sales
  • Give it plenty of space – this plant likes to spread out
  • Mulch around young plants to help retain moisture during establishment
  • Cut back spent flower stalks after blooming to encourage tidier growth
  • Be patient – it may take a year or two to really get established and show its full glory

The Bottom Line

Hall’s mule-ears is a spectacular native plant that deserves a place in California gardens, but only when grown responsibly. Its vulnerable status means we need to be thoughtful about how we obtain and grow it.
