TL;DR
This article highlights seven fire-resistant plants suitable for challenging yards, focusing on their durability and role in fire-smart landscaping. Confirmed by horticultural experts, these plants can reduce fire risk while maintaining garden beauty.
Seven plant varieties recognized for their fire-resistant properties are recommended for challenging yards to reduce wildfire risk, according to recent expert guidance. These plants, including white sage and snow-in-summer, are confirmed to withstand heat and sparks, making them valuable additions to fire-smart landscaping.
Experts from Homes & Gardens and fire ecology specialists have identified seven plants that are particularly resistant to heat and sparks, which can help mitigate wildfire spread in vulnerable areas. These include low-growing, moisture-rich plants such as rock soapwort (Saponaria ocymoides), white sage (Salvia apiana), and snow-in-summer (Cerastium tomentosum).
Rock soapwort, for example, contains natural soap in its leaves, which decreases flammability, and forms a compact, spreading mat suitable for gravel and sunny borders. White sage, a native drought-tolerant shrub, has high water content in its leaves, making it less likely to ignite. Snow-in-summer is a drought-resistant groundcover with high water content, thriving in hot, dry conditions and capable of suppressing fire spread.
Why It Matters
Choosing fire-resistant plants is a key element of fire-smart landscaping, especially in areas prone to wildfires. These plants can act as barriers by not fueling fires, thereby protecting property and lives. Their use can also reduce maintenance and water needs, supporting sustainable gardening practices.

Background
Wildfire risk has increased in many regions, prompting homeowners and landscapers to adopt fire-smart strategies. Experts emphasize planting native, moisture-rich, and low-growing plants that can withstand high temperatures and reduce fire spread. Previous wildfire events, such as California’s 2018 Camp Fire, have underscored the importance of fire-resistant landscaping.
“Fire-resistant plants can act as radiant heat screens and absorb more of the heat of an approaching fire without burning.”
— Adrienne Edwards, plant ecologist
“Healthy, sufficiently hydrated plants are less likely to ignite, which is why native, drought-tolerant species are recommended.”
— Rachel Schleiger, restoration ecologist

Key Questions
Are these plants completely fireproof?
No, no plant is completely fireproof. These plants are considered fire-resistant or fire-retardant, meaning they are less likely to ignite and help slow the spread of fire when used appropriately.
How should I plant these to maximize fire resistance?
Plant them with adequate spacing, use non-flammable ground cover like gravel or rocks between plants, and maintain regular pruning and debris removal to reduce fire risk.
Can these plants be used in any climate?
Most of these plants, such as white sage and snow-in-summer, thrive in zones 3-9. It is important to select species suitable for your local climate for optimal growth and resistance.
Do these plants require special maintenance?
Generally, native, drought-tolerant plants like these require less water and maintenance, but regular pruning and debris clearing are recommended to maintain their fire-resistant properties.
