Enter your ZIP to see whether this is legal to plant in your state, and whether it survives your winter.
Cichorium intybus has one CO row on the legal-list. That state-level entry opens the chicory record without implying the same legal status in another jurisdiction.
Its accepted fire sources remain limited evidence, and one ecological invasive report accompanies the local-list row. The evidence table keeps these lineages inspectable without converting the ecological observation into a fire conclusion.
The related plants section and range evidence add comparison and distribution context. Those destinations do not increase the single legal-row count or the one ecological report attached here to this individual species profile.

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.
Source location: PlantCharacteristics record 33521, Temperature, Minimum (°F).
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.
