The five hardest houseplants to kill

New to houseplants and scared of killing them? Start here. Five near-indestructible plants, their real light and water needs, and an honest pet-safety note for each.

If you've killed a plant before and quietly decided you're "just not a plant person," we'd like to gently disagree. Most houseplant deaths aren't a character flaw. They're usually one honest mistake — too much water, given too kindly — and the good news is that some plants barely notice.

These five are the ones we hand to nervous beginners. They cope with low light, they forgive a missed watering (or several), and they ask almost nothing of you. We've noted the real light and water needs for each, plus an honest word on pets, because "easy" and "safe around the cat" are not the same thing.

One theme runs through all of them, so we'll say it now: with these plants, under-watering is a minor wobble. Over-watering is what actually kills.

  1. Snake plant (Dracaena trifasciata). The closest thing to a houseplant that runs on neglect. It handles everything from a dim hallway to bright indirect light, and it stores water in those stiff upright leaves, so it genuinely prefers to be left alone. Water only when the soil is bone dry — roughly every two to three weeks, less in winter. Honest pet note: the snake plant is mildly toxic to cats and dogs (saponins), causing drooling or an upset stomach if chewed, so site it out of reach of determined nibblers.
  2. Pothos (Epipremnum aureum, "devil's ivy"). A trailing plant that seems almost impossible to discourage. It grows happily in low to bright indirect light, and it kindly tells you when it's thirsty — the leaves go soft and droopy, then perk back up within hours of a drink. Let the top few centimetres of compost dry out between waterings. Honest pet note: pothos is toxic to cats and dogs (insoluble calcium oxalates), so chewing brings mouth irritation and drooling — best kept trailing from a high shelf.
  3. Spider plant (Chlorophytum comosum). The one we reach for when there are pets or small children about, because it's the genuinely safe pick here — the spider plant is non-toxic to cats and dogs on the ASPCA's own list. It likes bright indirect light but tolerates less, and wants watering when the top inch dries. As a bonus it sends out baby "spiderettes" you can snip off and pot up for free.
  4. Peace lily (Spathiphyllum). The drama queen that's easier than it looks. It flowers even in fairly low light and, like pothos, collapses theatrically when thirsty then springs back after a water — so it more or less trains you. Keep the compost lightly moist, not soggy. Honest pet note: despite the name it isn't a true lily, so not the type that's acutely deadly to cats — but the peace lily is toxic to cats and dogs via calcium oxalates, causing mouth irritation and drooling if chewed.
  5. Aloe vera. A succulent that actively wants to be ignored. It's the one exception on light — give it the brightest spot you have, ideally a sunny windowsill — but on water it's pure forgiveness: a deep drink only when the soil has fully dried, roughly every two to three weeks. Soggy roots are the only real threat. Honest pet note: aloe is toxic to cats and dogs (saponins), so the odd chewed leaf can mean vomiting or lethargy.

01The one thing that actually kills them: kindness

Notice what every plant above has in common. None of them died of thirst. The single most common way to lose a "hard to kill" houseplant is to love it with the watering can — soggy compost suffocates the roots, they rot, and by the time the leaves yellow it's often too late. When in doubt, don't. Stick a finger in the soil; if it's damp, walk away. These plants would rather be forgotten than drowned.

Save your money

You don't need grow-lights, moisture meters, self-watering gadgets or special feed to keep any of these five alive. A normal windowsill, a pot with a drainage hole, and a watering can you use sparingly is the entire kit. Spend the money on a second plant instead.
