Society garlic is rated fire resistant across six assessments, including laboratory testing and regional plant guidance.
The University of Exeter wildFIRE Lab placed society garlic in its green, low-risk class even during drought. Prolonged burning at high temperatures is the hazard considered by Sun City Texas Firewise Group, which rates society garlic low for how readily it burns under those conditions. These findings directly address fire behavior, though through different rating systems.
The Diputació de Girona and Catalonia’s fire service recommend the plant through a broader garden-suitability method. That method combines fire evidence and professional experience with fuel structure, maintenance, origin, invasiveness, and species-specific care. Five earlier references recommending society garlic for high-fire-risk areas appear in a University of California Forest Products Laboratory compilation. The compilation also warns readers about the underlying plant lists’ undefined terms and frequent lack of scientific basis.
FireSmart BC calls society garlic FireSmart-approved while flagging it as needing more research. Fire Safe Marin also lists it as fire resistant, but says placement, spacing, irrigation, and removal of dead material remain necessary. Taken together, the sources support choosing society garlic as a fire-resistant perennial while continuing the maintenance required around a home.

Fire-resistant — location does not change the cited classification.
The guide presents itself as fire performance ratings for common landscape plants in a fire-prone California setting. FireApproved publishes 104 exact owners as republished California context. It is not an independent rating, a current endorsement, or parcel suitability.
Marin County (CA footprint); partial normalized coverage · 2019-01-01
The publication is explicitly limited to plants common to Marin County. FireApproved publishes 104 exact owners as Marin regional context while retaining its placement, spacing, irrigation, and maintenance boundary. It is not statewide California guidance or parcel suitability.
The UC Forest Products Laboratory says the guide covers properties of common California landscaping plants and was prepared for California fire agencies. FireApproved publishes 130 exact owners at historical California publication scope. The report is a 1997 compilation, not a current endorsement, site rating, or independent test of every row.
Sun City Texas, Georgetown (TX footprint); partial normalized coverage · 2015-01-14
The guide is authored for the Sun City Texas community in Georgetown. FireApproved publishes 142 exact owners only as community-level context. It is an archived HOA exhibit with unknown rating lineage, not a current statewide Texas source or an independent Tier 1 determination.

How to read this page
The status above is computed from the cited rows below: independent recommendations can support a fire-resistant result, an avoid row can produce keep-away, and disagreement stays visible as conflict. Placement notes preserve each source’s own scheme rather than translating unlike rules into one scale. This is evidence about a plant, not permission to plant it in every part of the defensible space; Zone 0 remains noncombustible.
Conditions in the fire evidence
These describe tested or rated plant material. They are not horticultural maintenance instructions.
Placement rules below use each source's own distances or named zones, tied to its rating.
They are not interchangeable with the directory's current Zone 0 guidance.

The evidence
Grouped by what each source concluded. Primary evidence rated the plant itself
(a lab, field program, or original curation); corroboration compiled or
republished another source's rating and resolves to its root lineage.
Tulbaghia violacea is rated “RECOMENDADA” by the guide's qualitative IUF garden-suitability method. The method assumes species-specific care and integrates fire evidence with fuel structure, maintenance, origin, invasiveness, and expert fire-service experience.
The table rates Society Garlic — Tulbaghia violacea low for flammability hazard, defined as the ease a plant can burn at high temperatures for a prolonged time.

“Table 1: favorable fire performance rating in 3 or more references (refs 8,9,25,40,41)”
The Diablo Firesafe Council Guide to Plants lists Tulbaghia violacea (Society garlic) as shrub, perennial, in Table 1: plants with a favorable fire performance rating in 3 or more references. The guide cites 5 of its 57 numbered references for this row (8,9,25,40,41). The guide states the ranking terms in its underlying references were mostly undefined and makes no attempt to rank within the list, and that fire performance is compromised without maintenance.
