Best plants
Almost every first houseplant dies of the same two things: too little light and too much water. These species forgive both, which is exactly what a beginner needs.
How this list is built: houseplants that are both low-light tolerant and drought-tolerant — the two failure modes that kill most first plants— filtered from Growli's structured plant-care library, not hand-picked, so it stays consistent and checkable.

This list is not hand-picked for looks. It is houseplants that are both low-light tolerant and drought-tolerant — the two failure modes that kill most first plants, drawn from Growli's structured plant-care library so the selection is consistent and checkable. 731 plants qualify today.
Growli currently lists 731 plants that meet the criterion (houseplants that are both low-light tolerant and drought-tolerant — the two failure modes that kill most first plants). The list updates as the plant-care library grows; each entry links to a full care guide.
Not necessarily — this list is selected by houseplants that are both low-light tolerant and drought-tolerant — the two failure modes that kill most first plants, not by pet safety. Each plant is tagged with its pet-safety status below, and links to a full ASPCA-sourced pet-safety guide. If you have pets, see the dedicated best pet-safe houseplants list.
Once you have shortlisted a plant, the next questions are watering and soil. These are the guides searched most this season:
