How to read a plant page

Last verified 2026-08-26.

A plant page is not a listing. The banner is a computed status. The rows under The evidence are the votes. How to read a listing is the materials sibling: a test method is not a listing, and a listing is not adopted code. This page is the plant sibling: a Firewise PDF is not a lab, a reprint is not a second lineage, and on-list is not fireproof.

You are on Vitis looking at Documented conflict and at a chip that says 8 of 10, and wondering which one “wins.” Neither is deleted. Open the rows.

Why it matters

If you read only the banner, you miss the fight. If you count every PDF as a new vote, you invent a majority. If you “fix” verdictRaw, a condemning list can vanish. Methodology is the rule. The plant page is where it shows.

How it works

Walk Vitis top to bottom.

1. The banner. Labels come from recommendation:

BannerWhat it means
Fire-resistantOn-list. Independent lineages recommended it
Keep awayAvoid. Independent lineages condemned it
Documented conflictLineages disagree, or lab dissent cannot be silently outvoted
Awaiting evidenceCandidate. No directional primary verdict yet

Vitis currently computes as conflict (ratingReason: disputed). The page also prints Computed class: Mixed evidence. That class is derived. It is not a third grade between on-list and avoid.

2. The tally chips. Each chip is one independent Tier-1 lineage and a direction (recommend, avoid, split, or mid-scale). A “fire-tested” mark means that lineage is lab, field-trial, or post-fire evidence. Copies of the same rater share a chip. See the Steward rule.

3. The evidence groups. Rows are grouped as Recommends, Avoids, Mid-scale / conditional, or Listed without a rating. Primary evidence rated the plant. Corroboration republished someone else and resolves to the root.

4. verdictRaw. The quoted sentence on each row is the source’s letters. Idaho Firewise on Vitis is stored as fire-resistance score 8 of 10. An FPS typo stays in verdictRaw so it cannot drop a lineage. See source-verbatim names.

5. original. If a row names another source as original, it is a reprint. It does not vote twice. On Amelanchier laevis, the NCSU row is stored with original: bardon-2005.

6. Placement. “Where its sources say to plant it” keeps each list’s own scheme (Idaho 30 feet, FPS LZ2, B921 Zone 3). Those distances are not translated into one scale, and none of them is Zone 0.

7. Invasive warning. If it appears, a fire rating does not override it.

8. The local evidence lens. Read it as separate questions, in order:

DimensionWhat a positive row establishesWhat it does not establish
State distributionThe source documents current occurrence in the stateNative status, hardiness, or a recommendation
Native rangeA current cited source names the state as native rangeFire performance or permission to plant
Introduced / establishedA source names the state as introduced or establishedAn invasive warning by itself
USDA hardinessThe selected source statement can be compared with the ZIP’s USDA zoneA fire rating, water advice, or local approval
Reported invasive hereAn exact-state ecological row names the plantA legal prohibition
Legal-list status — for example, Prohibited here or Regulated hereAn exact-state legal-list row names the plant, authority, and exact designationEcological severity or a permit decision
Regional / federal contextA broader source applies at its own grainAn exact-state finding

A minimum hardiness value is a cold threshold, not a one-zone range and not an invented maximum. Different compatible source ranges stay separate as overlapping. Applicable source ranges with no shared zone stay conflicting, with no primary range chosen. Compare Acer circinatum and Aronia melanocarpa.

9. Fire conditions and FEIS. A green, irrigated, cured, or dead condition belongs to the cited fire-evidence row. It never becomes horticultural maintenance advice. FEIS context is another distinct layer: exact-taxon, section-reviewed statements about ecosystem or fuels, immediate fire effects, postfire response, management, or invasive–fire feedback. On Arundo donax, the linked USDA Forest Service review remains context only and never casts another recommendation vote.

The same chrome on Salvia rosmarinus is why conflict stays visible instead of averaging 5 feet and 30 feet. See why rosemary is disputed.

What people mix up

  • The banner as a hand-assigned FireApproved grade.
  • Fire-resistant on a plant page as an OSFM listing.
  • Counting every evidence row as a lineage.
  • Averaging conflict.
  • Treating limited-evidence as unrated.
  • Treating candidate (awaiting evidence) as limited-evidence. Candidate means no directional primary verdict yet.
  • Reading placement schemes as Zone 0.
  • This guide as a reprint of how to read a listing.

How to check

  1. Open a plant page. Name the banner label.
  2. Count chips, not filenames.
  3. Open one row. Read verdictRaw in the quoted line. If original is present, it resolves to the root.
  4. Open methodology if you need the tally rule in prose.
  5. For materials, switch to how to read a listing. Confirm the model number there. Confirm the taxon here.

Limits

This page walks the plant-page chrome and quotes the stored Vitis Idaho Firewise 8-of-10 row. It does not re-open every Vitis or rosemary lineage. It does not reprint 161 cards. It does not decide a planting. Zone 0 is not a planting list.


Questions

Is the banner a FireApproved rating?

No. The banner label (Fire-resistant, Keep away, Documented conflict, Awaiting evidence) is computed from independent Tier-1 lineages by a published rule. It is never hand-assigned.

What are the chips under the banner?

Each chip is one independent primary-evidence lineage and its direction. A reprint does not get its own chip. A lineage that points both ways is split and votes for neither.

What is verdictRaw?

The source’s own words or score, stored as spelled. On Vitis, Idaho Firewise is stored as fire-resistance score 8 of 10. We do not rewrite that into Firewise (1).

What does original mean on a row?

The row is a reprint. It resolves to the root lineage named in original. It does not add a second vote.

Is this the same as how to read a listing?

No. A listing is a named model on a listing body’s current record. A plant page is evidence about a taxon. Do not treat on-list as an OSFM listing ID.

Does documented in my state mean native or suitable for my ZIP?

No. Distribution, native or introduced range, and USDA hardiness answer separate questions. A ZIP adds a hardiness comparison; it does not create a planting approval.

Does no invasive or legal-list row mean the plant is clear?

No. Exact-state ecological reports, exact-state legal records, broader regional context, and source silence remain separate. Missing evidence is not clearance.

Does FEIS fire ecology change the fire-resistant banner?

No. Section-reviewed FEIS context can describe fuels, immediate effects, postfire response, management, or invasive–fire feedback. It never votes in the computed plant classification.
