How We Research and Write

Data-Driven, Not Opinion-Driven

Every care recommendation we publish is traceable to a primary source: botanical references, horticultural extension services, peer-reviewed research, or well-documented cultivar data. We do not base guides on anecdote, social media consensus, or "it worked for me" reasoning.

Where the data conflicts — for example, watering frequency recommendations that vary across reliable sources — we note the range and explain what the key variables are, rather than picking an arbitrary middle number and presenting it as definitive.

What "Verified" Means Here

Before a species guide is published, The PlantAtlas Field Desk cross-references at least two independent sources for each care parameter (light, water, soil, humidity, feeding). We prioritize university extension programs, botanical garden care sheets, and species monographs over generalist gardening sites.

Guides are reviewed for accuracy when a species is reclassified (e.g., the Sansevieria→Dracaena reclassification), when new cultivar data emerges, or when a reader submits a well-sourced correction.

Toxicity Claims

Toxicity information is one of the highest-stakes areas in plant care publishing. We source toxicity data from the ASPCA Animal Poison Control Center database, the USDA PLANTS database, and peer-reviewed toxicology literature. We distinguish between "toxic to cats and dogs" (ASPCA-confirmed) and "mildly irritating" or "toxic in large quantities" — and we note the difference rather than flattening all risk into one category.

Toxicity data is an input for decision-making, not a substitute for professional advice. If a pet or person has ingested a plant, contact a veterinarian or Poison Control immediately. Our toxicity ratings are for reference only and should not be the sole basis for an emergency decision.

Corrections Policy

We correct factual errors as soon as we become aware of them. If you find something wrong — a misidentified species, an inaccurate care parameter, an outdated taxonomic name — please contact us with a source and we will review and update the guide promptly.

Commercial Relationships

PlantAtlas participates in the Amazon Associates program and may participate in other affiliate programs in the future. Affiliate links are used only in our gear recommendations. Care guide content — light, water, soil, propagation, and troubleshooting — is never influenced by commercial relationships of any kind.
