Late Lilac is on-list in the cited row. The 2006 source gives Syringa villosa a low-flammability direction and also describes it as disease sensitive.
A separate temperature measurement of -38°F maps to an applicable 3a hardiness minimum. That measurement concerns climate tolerance, not fire performance, and does not expand the single directional row in the evidence table.
One ecological report separately records introduced-established status across the lower 48. The stored state entries name MA, NY, and OH. The page remains limited evidence, and the source row preserves both the low-flammability classification and the disease note.

Typed publication scope: 1 scope across 1 cited fire source
Ohio State University Extension Bulletin 921 is an Ohio publication that describes Ohio fire seasons and landscape conditions and labels nativity to Ohio. FireApproved publishes 352 exact source-owning plant records from its eight rated tables. This historical publication scope does not assert current extension endorsement or that a listed plant suits every Ohio site.

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.
Plant hardiness evidence
These values describe the plant source. Your ZIP zone comes from the separate 2023 USDA
Plant Hardiness Zone Map. Whole-zone values stay whole-zone, and a single unresolved value
is not treated as a tolerance range. Different source boundaries stay separate: overlapping
statements are compared independently, while only ranges with no shared zone are called a conflict.
Source location: PlantCharacteristics record 49902, Temperature, Minimum (°F).
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.
