Best plants
A steamy bathroom or kitchen is wasted on a cactus. These species genuinely want the higher humidity that most homes only have in those rooms — or near a humidifier.
How this list is built: houseplants whose documented ideal humidity is 50% or higher— 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 whose documented ideal humidity is 50% or higher, drawn from Growli's structured plant-care library so the selection is consistent and checkable. 4056 plants qualify today.
Growli currently lists 4056 plants that meet the criterion (houseplants whose documented ideal humidity is 50% or higher). 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 whose documented ideal humidity is 50% or higher, 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:
