Your local evidence lens
Separate evidence questions, never one approval badge
A genus split is not a placement verdict. Set a ZIP to read the local documented split.
1. Fire evidence and conditions
- Fire evidence
- Mixed evidence — location does not change the cited classification.
- Fire-performance conditions
- No test or rating condition is normalized.
- Fire ecology context
- No section-reviewed fire-ecology context is normalized.
- Placement evidence
- 0 source placement records; source schemes remain separate.
- Evidence regions
- Global
- Maintenance
- No sourced horticultural maintenance assertion is normalized; fire-test conditions do not supply maintenance advice.
2. Why this plant is relevant here
- State distribution
- Documented in AK, AL, AR, AZ, CA, CO, CT, DC, DE, GA, IA, ID, IL, IN, KS, KY, LA, MA, MD, ME, MI, MN, MO, MS, MT, ND, NE, NH, NJ, NM, NV, NY, OH, OK, OR, PA, RI, SC, TN, TX, UT, VA, VT, WA, WI, WV, WY.
- Native range
- No current cited or legacy state native range is normalized.
- Introduced / established
- 48 sourced range or established records; set a location to match them. This is not an invasive warning.
- USDA hardiness
- Documented minimum 3a; 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
- 1 ecological invasive report; 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 (4)
- NH · Seed-list name scope unresolved. An exact source taxon is governed by “Undesirable Grass 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.
- PA · Seed-list name scope unresolved. An exact source taxon is governed by “Restricted (Undesirable Grass Seeds) in lawn and turf 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.
- VA · Seed-list name scope unresolved. An exact source taxon is governed by “Restricted - Lawn and turf seed only” 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.
- WV · Seed-list name scope unresolved. An exact source taxon is governed by “Restricted Noxious-weed Seed in Lawn and Turf Seed and Mixture” 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.
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.
