Why This Plant?
A California native fern for shaded, seasonally moist microclimates. It can provide low, leafy cover beneath trees and in sheltered garden areas, with growth typically responding to winter and spring moisture.
No plant is fireproof. Fire-resilient landscaping combines the right plant in the right place, with appropriate spacing, irrigation, and ongoing maintenance.
Firewise Maintenance Notes
Remove dead or dying material and accumulated plant litter regularly; maintain healthy growth and appropriate spacing so vegetation does not form continuous horizontal or vertical fuel. Keep plantings open and free of accumulated dry debris, particularly near structures.
Defensible Space Context
Placement, spacing, density, moisture and maintenance determine fire performance
