The houseplant difficulty index
All 110 houseplants we cover, ranked from nearly unkillable to full diva. No invented star ratings: each plant is scored by the language of its own care guide - how often the profile reassures ("tolerates neglect", "hard to kill") versus warns ("fussy", "won't tolerate") - written long before this index existed. Method disclosed in full below.
🛡️ Nearly unkillable (27)
Ease language everywhere, warnings almost nowhere. Forget one for a fortnight and it forgives you.
😌 Easy going (31)
Solidly forgiving - a sensible first shelf.
🙂 Middle of the road (25)
Fine once you know its one or two preferences.
🧐 Wants attention (14)
Readable, but the guide starts using its careful voice.
👑 The divas (13)
More warnings than reassurance. Gorgeous - and they know it.
📐 Methodology, in full
Each of our 110 houseplant guides was scanned at build time, so this page recomputes whenever a guide changes. We count ease phrases - hard to kill, indestructible, unkillable, forgiving, easy, low-maintenance, neglect(-proof), beginner, undemanding, unfussy, fuss-free, carefree, drought-tolerant, adaptable, resilient, tough, hardy, survives, tolerates, tolerant, weeks without - and warning phrases - fussy, demanding, tricky, challenging, diva, not for beginners, difficult, temperamental, picky, unforgiving, experienced growers, dramatic, sensitive to, prone to leaf drop or sulking. Negated ease ("won't tolerate", "rarely survives") is counted against. Score = ease minus warnings; tiers are fixed score bands.
Limits, honestly: this measures how our writers talk about a plant, not a lab test; longer guides get more chances to score; and difficulty depends on your home - a "diva" beside a humidifier is easier than an "easy" plant over a radiator. Use the tiers as a shortlist, check the light with the window light guide, then read the full profile. Choosing between two? Put them in the comparison tool.
