Jersey tea is rated fire resistant, though the support comes from two plant lists and one calls for more research.

FireSmart BC approves Jersey tea as a fire-resistant plant, but also flags it as needing more research. Its chart is a compiled, yes-or-no guide covering 290 plants and assigning suitable Home Ignition Zones where possible. Approval is a useful recommendation for landscaping, but the research flag makes clear that it is not a final judgment backed by extensive study.

Utah State University Extension also lists Jersey tea as a firewise choice for Utah landscapes when it is properly placed and maintained. That source is an expert-curated list of 83 plants or plant groups rather than a direct flammability experiment. The agreement between two regional programs supports the fire-resistant rating, while their methods explain why the conclusion remains limited.

Jersey tea is a shrub in the buckthorn family, Rhamnaceae. For a homeowner, the practical reading is reassuring but conditional: two institutions accept it for fire-conscious planting, yet neither finding makes placement and upkeep irrelevant, and FireSmart BC still sees unanswered research questions.

3. Legal, ecological, and broader status

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.

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.
