Best plants
A trailing plant turns a shelf edge or a bare wall into something alive. These are the vining and climbing species in our library, with the support each one wants.
How this list is built: houseplants with a documented trailing, vining, or climbing growth habit— 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 with a documented trailing, vining, or climbing growth habit, drawn from Growli's structured plant-care library so the selection is consistent and checkable. 1461 plants qualify today.
Growli currently lists 1461 plants that meet the criterion (houseplants with a documented trailing, vining, or climbing growth habit). 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 with a documented trailing, vining, or climbing growth habit, 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:
