Fire-Resistant Plants
The best fire-resistant plants by type — and the high-flammability species to keep away from your home. Remember: it’s characteristics, placement, and maintenance, not a magic plant.
What makes a plant fire-resistant
Lower-flammability plants share these traits — but maintenance and placement matter most.
- ✓High moisture content in leaves and stems
- ✓Low sap, oil, or resin content (resinous plants burn hot)
- ✓Little dead wood or fine dead material that accumulates
- ✓Low-growing and open rather than dense and twiggy
- ✓Easy to keep pruned, watered, and free of litter
Fire-resistant plants by type
Groundcovers
Ice plant, creeping/woolly thyme, sedum/stonecrop, ornamental strawberry, low-growing ceanothus
Perennials & flowers
Lavender, yarrow, coral bells (heuchera), daylily, society garlic, columbine, salvia, penstemon, lupine
Succulents
Agave, aloe, hens-and-chicks, jade — high water content, very slow to ignite
Shrubs (well-spaced)
Rockrose, California fuchsia, currant, spicebush, hummingbird sage — kept low and separated
Trees (deciduous hardwoods)
Maple, dogwood, redbud, cherry/plum, poplar, aspen — generally more fire-resistant than conifers
Choose species suited to your climate and water; check your state forestry or university-extension list for regional picks.
High-flammability plants to avoid near the house
Keep these out of the first 30 feet (Zones 0–1) entirely.
- ✕Juniper (any) — resinous, accumulates dead material
- ✕Italian cypress & arborvitae — dense, oily, “torch” plants
- ✕Eucalyptus — high oil, sheds bark/leaves
- ✕Pine, fir & most conifers — resinous needles and litter
- ✕Rosemary (large) & other oily woody herbs en masse
- ✕Pampas grass & fountain grass — fine dead thatch
- ✕Bamboo — fast-burning, hard to contain

Fire-resistant plants FAQ
What makes a plant fire-resistant?
Fire-resistant plants tend to have high moisture content, low sap/oil/resin, and little accumulated dead material, and they stay low and open. But “fire-resistant” is relative — any plant will burn if it’s dried out, dead, or unmaintained. Characteristics plus watering, pruning, and spacing are what make a planting truly resistant.
Are there fireproof plants?
No. CAL FIRE and university extensions are clear that no plant is fireproof. The goal is choosing lower-flammability species, then placing and maintaining them so fire can’t easily spread through them — especially in the first 30 feet around the home.
What are the worst plants to have near a house?
High-oil and resinous evergreens and fine-dead-fuel plants: juniper, Italian cypress, arborvitae, eucalyptus, pine, large rosemary, bamboo, and grasses like pampas and fountain grass. These are notorious for igniting fast and throwing embers — keep them out of Zone 0–1 entirely.
Do fire-resistant plants differ by region?
Yes — choose species suited to your climate and water, ideally natives or low-water plants that stay healthy without heavy irrigation. Your state forestry agency or local university extension publishes region-specific fire-resistant plant lists; we link to those resources from the defensible-space guide.
