Will be stronger is screwed into wood, or a stud, but can be used for drywayll, Especially important for drywall, that you don’t over stress the hook, and the planter fall and become a safety hazard.
These hooks, only hold about 15lbs in drywall, or 30lbs in wood. so safety is the first thing to think about. The weight limit, keep in mind, when you give it some water, how much does that add to the weight.
Keep in mind, if you are in an area, with strong winds or earthquakes, that your planter doesn’t become a swinging weapon.
