Have you ever come across a plant that is so attractive that you can’t resist getting one for yourself? But, as soon as you bring it home, you realize that it’s not just any ordinary plant, it’s a total diva! 

That’s right, I’m talking about the ZZ plant. This plant is not only a showstopper, but it also has a reputation for being toxic to other plants.

The ZZ Plant’s Bad Reputation

The ZZ plant has a bad reputation for being toxic to other plants because it releases a chemical called allelopathic substance that can affect the growth of other plants. 

Allelopathic substances are produced by some plants to prevent other plants from growing near them, thus giving them an advantage in terms of light, water, and nutrients.

The allelopathic substance released by the ZZ plant can slow down the growth of other plants, but it’s not a death sentence for them. It’s just a way for the ZZ plant to maintain its position as the queen of the plant world.

Not just for other plants, ZZ plants can be toxic to your pets such as cats and dogs as well!
