Let’s find the best indoor plants for you

How we come up with the results (our process for transparency)

The recommendations this tool surfaces aren’t based on guesswork. Every plant in our database is tagged across six variables — light tolerance, growth habit, pet safety, watering needs, humidity preferences, and experience level — and each tag is cross-referenced against authoritative horticultural sources before it goes in.

Light is the variable most plant advice gets wrong. We use placement rather than window direction because placement is what actually determines how much light reaches your plant. A south-facing window means nothing if your plant is across the room. Our light thresholds are grounded in research from the University of Missouri Extension, which establishes that light intensity drops dramatically with distance from the source — a plant a few feet back from a bright window may be receiving as little as a quarter of the light available at the sill.

Pet toxicity is sourced directly from the ASPCA Animal Poison Control Center, the most comprehensive and consistently updated database of plant toxicity for cats and dogs. If a plant is listed as toxic there, we tag it toxic — no exceptions, no rounding down.

Watering and humidity needs draw on the Royal Horticultural Society’s plant care database, which provides detailed species-level guidance on moisture requirements. For plants where RHS data was limited, we supplemented with guidance from Clemson University’s Home and Garden Information Center, one of the most thorough university extension resources available for indoor plant care.

Experience level is our own judgment, informed by years of growing these plants in our Brooklyn brownstone alongside dozens of others. A plant tagged as experienced isn’t necessarily difficult — it’s one where the margin for error is narrower, where recovery from neglect or overwatering is harder, or where getting the conditions right requires more attention than a beginner is likely to give. We’ve killed enough of them to know.

The scoring algorithm weighs all six variables simultaneously. Light and vibe carry the most weight because they’re the hardest to compensate for — you can adjust your watering habits, but you can’t move your windows. Pet safety is a hard filter, not a score: if you have curious pets, toxic plants are removed from your results entirely, not just ranked lower.

Every recommendation is a real plant we have grown, observed, or researched in depth. Nothing in this database is filler.
