Native range
No current cited or legacy state native range is normalized.
Introduced / established
52 sourced range or established records; set a location to match them. This is not an invasive warning.
USDA hardiness
No hardiness value is normalized.
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
26 state noxious-weed seed records; set a location to match exact scope.
Reported invasive here
3 ecological invasive reports; set a location to distinguish exact from regional context.
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.
Plant-specific state seed-list reviews (1)
These source-bound receipts answer only the July 2026 state noxious-weed seed-list question. They do not establish non-seed plant legal status, ecological invasion, nursery-sale rules, or unrestricted use.
PA · Seed-list name scope unresolved. An exact source taxon is governed by “Restricted in agricultural seeds” or an applicable source note, so the qualified row is held instead of publishing an unconditional result. This answers only whether the plant identity appears in the July 2026 state noxious-weed seed sheet. It does not establish non-seed plant legal status, ecological-invasive status, nursery-sale rules, or unrestricted use. Held source row: usda-ams-state-noxious-weed-seed-2026:PA:029. Governing seed section: Restricted in agricultural seeds; normalized seed-kind scope: agricultural seed and named companions; applicable note rows usda-ams-state-noxious-weed-seed-2026:PA:035.Official USDA seed requirements.Normalized source record.
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.
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.
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.
