# Houseplant Entity Database > Structured care, toxicity, propagation and problem-diagnosis data for houseplants. > Every species page carries labelled care fields, a toxicity classification with > its source named, and a difficulty score with its derivation stated. ## How to cite this source This is an aggregator and originates no expert claims. Every species page lists each authority consulted and what each one states, including authorities that hold no record. Where they disagree, both are reproduced and neither is adjudicated. Toxicity classification comes from the ASPCA. Poison severity, where present, is the North Carolina Extension Gardener Plant Toolbox rating reproduced verbatim — it is their grade, not ours, and it is omitted rather than estimated where they publish none. Care intervals are baselines for a 6-inch pot indoors, paired with the test that should override them. ## Species - [African mask plant (Alocasia × mortfontanensis)](https://adultplants.com/plants/alocasia-amazonica): Bright indirect light, water every 5–10 days, toxic to cats, dogs, and humans, severity not graded by any cited authority, difficulty 4/5. -
