Siberian wheatgrass is rated fire resistant, but that rating rests on its use in managed greenstrips rather than direct burn testing.
The USDA Natural Resources Conservation Service, University of Nevada Cooperative Extension, and Society for Range Management all identify Siberian wheatgrass as a plant used in greenstrips in the Great Basin or Intermountain West. These are expert-curated recommendations for a specific setting, not unconditional endorsements for planting beside a home. The range-management article also says it does not report a separate burn result for the species.
Management is central to the favorable rating. Nevada’s extension service says greenstrips should be grazed or mown often enough to reduce fuel. That condition matters because the source is recommending a maintained planting system, not claiming that Siberian wheatgrass remains resistant regardless of upkeep. The USDA describes it as a tall, long-lived bunchgrass suited to annual precipitation of 8 to 16 inches and several soil textures.
Siberian wheatgrass is a low-water grass in the Poaceae family, reaching about two feet at maturity. It is introduced in seven states, including Colorado, Idaho, and New Mexico, and is hardy to USDA zone 2b. The practical conclusion is narrow: it has credible support as a maintained greenstrip plant, but the sources do not establish its performance in an unmanaged residential planting or provide a species-specific burn test.

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.
The lossless worldwide derivative is retained once in the research corpus; object pages repeat only exact U.S. areas needed by the local lens. The JSON twin carries the same page assertions.
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.

Where its sources say to plant it
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.
“Common perennial plants used in greenstrips and selected characteristics important to their establishment and use”
Table 1 row: Siberian Wheatgrass (Agropyron sibiricum). Minimum yearly precipitation: 8-10 inches; salt or alkali tolerance: Moderate; status: I; growth form, flower color, or season: Bunch; varieties: ‘P-27’. The fact sheet says greenstrips should be grazed or mown frequently enough to reduce fuel buildup; otherwise their effectiveness is reduced dramatically.
Table 1 row: Siberian wheatgrass — A. fragile (Roth) Candargy. The article says these are species frequently used in greenstrips; it does not report a separate burn result for this row.
