About this guide

Every plant page is labeled Still researching this plant, with visible evidence gaps and open questions in its agent notes. This allows useful, sourced working profiles to be published while uncertain taxonomy, pet effects and expert review remain explicit.

This independent guide covers 154 plant profiles relevant to Colorado yards, gardens, paths and disturbed land. It separates native volunteers, xeriscape spreaders and invasive and common weeds, while giving each plant dedicated sections for people, dogs and cats, other animals, and surrounding vegetation.

“Weed” describes a plant growing where someone does not want it. It does not erase that plant’s ecological value. Colorado native communities also differ across elevation, exposure and climate. A garden choice for one site may not fit another. CSU Extension: Native Plants.

The coverage checklist maps all 82 entries in Colorado’s reviewed A, B and C lists to illustrated profiles. Additional profiles cover common weeds, native hazards and xeriscape spreaders. Biggest concerns offers a practical starting point. Coverage of a listing includes documented taxonomic limits; it is not a claim that every subspecies or hybrid has been independently confirmed.

How the evidence is handled

Profiles are AI-assisted editorial syntheses of linked Extension, government, poison-control and veterinary sources. Independent botanical and veterinary expert review is pending. This is a selected catalog, not a complete flora, poison database or identification key.

Each factual section links its sources. The additional Markdown notes distinguish species-level findings, genus-level evidence, animal-group evidence, physical-risk inferences and unresolved questions. Source publication dates, retrieval dates and page revision times are kept separate.

Every plant has three distinct, source-identified photographs. Photographer credits and licenses appear beside the photos. We do not claim a photograph was taken in Colorado unless its source documents that location. Images are reference examples, not independent determinations of a visitor’s plant.

Built for people and their assistants

The site follows the published Stoagen pattern: readable static pages, a Markdown mirror with additional evidence notes, and visible links for agents. This is an independent implementation. All substantive profile content is available without JavaScript or a sign-in.

The source project lives in GitHub. Ordinary HTML, Markdown, JSON, CSS and image files can be served by another static host. No OpenAI hosting runtime is required.

Corrections and reuse

Propose a correction through the GitHub repository, including the scientific name, the claim in question and a supporting source. Source errors, taxonomic changes and new toxicology evidence should be recorded explicitly.

Photo licenses apply individually and are linked with each image. Third-party publications retain their own copyrights; this site paraphrases their facts and links to the originals. No blanket license over those sources or photographs is claimed.
