The other day I was curious to see what the growing requirements were for a couple Parnassia species and Trichophorum alpinum since they’re among my favourite plants and it would be neat to have them at home. I’ve seen photos of them growing both in gardens and indoors so I think it is possible, but there’s very little legitimate information out there about their growing requirements in cultivation because they’re pretty obscure.
But as you said, there are plenty of search results regardless. The websites “greg.app” as well as “picturethisai” and “plantingo” all have auto-generated fake growing requirements for any plant you search for. “GardenersHQ” seems older and probably actually typed out by a human, but the fact that it has standardized pages for so many species and only photos taken from elsewhere makes me suspicious that they’ve never actually tried growing most of the plants they cover.
Similar to the spider website, I assume these pages are all designed to get clicks either for ads or to funnel people towards some scam where they’ll pay for “expert advice” that doesn’t exist.
By the way ChatGPT was surprisingly accurate at identifying a plant photo I tried. Claude.ai was not, it thought the Parnassia were various carnivorous plants.
