Fire Resilient Landscaping Combines the Right Plant, Place, and Maintainance
No plant is completely fireproof. Fire-resilient landscaping combines the right plant in the right place, with appropriate spacing, irrigation, and ongoing maintenance.
This plant has been evaluated for its characteristics and potential use in wildfire-resilient landscapes, but its performance depends on site conditions—including slope, exposure, surrounding vegetation, proximity to structures, and how the landscape is maintained.
Use the information in this Plant Finder as a planning guide, not a guarantee of fire performance. Always follow current local requirements and site-specific guidance when designing or modifying vegetation around your home.
