Leersia virginica · Poaceae · Wikipedia

Fire-resistant. Recommended by the one independent primary-evidence lineage to have rated it so far (Combustion characteristics of north-eastern USA vegetatio…), with no objection on record. Limited evidence: a single lineage — more sources may still move this verdict. This status is computed from the cited evidence by the published rule, never hand-assigned.

▲ Combustion characteristics of north-eastern USA vegetatio… · fire-tested

Computed class: Fire-resistant (limited-evidence) — derived from the cited evidence by a published rule, never hand-assigned. Each chip above is one independent primary-evidence lineage and its direction. No plant is fireproof; condition and placement govern. Zone 0 is hardscape regardless.

Combustion characteristics of north-eastern USA vegetation tested in the cone calorimeter · Official scoped edition
- Northeastern and mid-Atlantic study sites (ME, MD, MA, NY, VA footprint); partial normalized coverage · 2007-08-20
  The authors collected foliage and twigs across study sites in Maine, Maryland, Massachusetts, New York, and Virginia, then conditioned and tested the samples in a cone calorimeter. FireApproved publishes 37 exact source owners only as multi-state laboratory context. The source does not establish that every taxon was sampled in every named state, whole-plant behavior, landscape suitability, or state planting guidance.

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.

Native and introduced range evidence

These are exact U.S. botanical-area records from the cited range source. Native and introduced describe biogeographic relationship, not fire performance or planting approval. Doubtful and extinct rows stay visible but do not count as current presence.

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.

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.
