API source score

Perenual API88/100optional key: Flower and ornamental drill-down, plant photos, care flags, toxicity, bloom data. Limit: Requires an API key and plan-aware caching, so it should enrich records without blocking the app.
Trefle API84/100optional key: Scientific names, subspecies, varieties, hybrids, synonyms, and broader botanical cleanup. Limit: Requires a token and should be treated as a reviewed import layer, not a live page dependency.
USDA PLANTS downloads82/100download cache: Standard names, plant symbols, distribution, native status, and conservation flags. Limit: Best consumed as periodic downloaded data instead of one-off runtime requests.
GBIF Species API78/100live public: Accepted scientific names, synonyms, family/genus cleanup, and occurrence context. Limit: Not a gardening advice source; pair it with local square-foot growing data.
iNaturalist taxa API72/100live public: Common-name discovery, taxon IDs, and regional biodiversity context. Limit: Observation data is not the same thing as garden suitability or crop timing.
