A houseplant reference that states its sources
25 species across 23 genera
Care intervals, light placement, toxicity with severity, and ranked problem diagnosis for indoor plants. Every fact is attributed to a named authority. We publish no horticultural or veterinary judgment of our own.
What is here
25 species, hand-built. This is the validation set, not the finished database.
Each species record carries labelled care fields, a difficulty score with its derivation stated rather than asserted, and a toxicity classification that separates an hour of mouth pain from organ damage. Light is given as placement — an east window, or a measured distance back from a south-facing one — because "bright indirect" is not an instruction anyone can follow.
Watering intervals are baselines for a 6-inch pot indoors, and every one is paired with the test that should override it. A plant in a bright room in July is on a different schedule than the same plant in November, and a number that ignores that is worse than no number.
How this is sourced
This is an aggregator, and it says so. Toxicity classifications come from the ASPCA. Care and pest guidance comes from university extension services and the Missouri Botanical Garden. Taxonomy comes from Kew and Wikidata, and every species carries a Wikidata identifier so its record can be matched against other sources rather than taken on trust.
Severity ratings are reported only where a named authority published them. We do not rank severity ourselves, and no page here is written by a veterinarian or a horticulturist. Where the honest answer is that the evidence is thin, the page says so instead of filling the gap.
