Corrections and sources

If a species profile or guide contains an error, tell us which page and which statement, and link the source that shows the correct information: a flora, an original description, a paper or an institutional publication. We check every correction against the source before changing the page.

What we cannot help with

We cannot identify plants from photos sent by email, and we do not give veterinary or medical advice. If a pet may have eaten a plant, contact your veterinarian or an animal poison control service.

Advertising and business enquiries

We do not sell sponsored posts or links. Ads on this site are served by Google AdSense; we do not choose individual advertisers.
