Travis County, Austin area (TX footprint); partial normalized coverage · 2024-01-16
Texas A&M AgriLife Extension publishes this page through its Travis County horticulture program. FireApproved publishes 56 exact owners and retains the source's zone and warning conditions. This is county/Austin regional context, not a second statewide Texas table or site clearance.
Current cited native range in AL, AR, FL, GA, LA, MS, NC, OK, SC, TX.
Introduced / established
No introduced or established row is normalized; that does not prove native status.
USDA hardiness
Documented minimum 7b; no upper limit is documented.
3. Legal, ecological, and broader status
Legal-list status
Set a location for an exact legal-list result; source silence is not clearance.
Seed-list status
Set a location to compare the separate state noxious-weed seed layer.
Reported invasive here
No ecological invasive report is normalized; that does not prove noninvasiveness.
Broader regional context
Aggregate AK, HI, and L48 evidence is shown only as regional context, never as an exact-state finding.
Federal context
Federal designations remain separate from state legal-list results.
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.

Evidence
3 cited sources
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.
Minimum 7b · no upper limit documented · half zone precision · derived containing band
Exact source measurement: 7°F; mapped only to its containing half-zone.
Source taxon: Sabal minor · source identifier match.
Source location: PlantCharacteristics record 16772, Temperature, Minimum (°F).
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.
Firewise Landscaping: Small trees; Small Shrubs; High Flammability Plants to Consider Avoiding for all Zones [Travis County Firewise page sections] (with its avoid rating)
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.
“High Flammability Plants to Consider Avoiding for all Zones”
Listed as Texas Sabal Palm or Palmetto — Sabal minor; Palmetto, Texas dwarf — Sabal minor; Palmetto — Sabal minor. The page says Zone 1 entries should be restricted to zones 2 or 3; all-zone entries are highly flammable due to volatile oils or growth habit.
2 cited rows from this source; its identity, lineage and tier are stated once.
