Ever wonder why Monsteras have holes? The technical name for this unique feature is called fenestration or leaf perforations. Researchers don’t have a concrete explanation for the evolutionary purpose of fenestration, but there are a few possibilities.
It could be that fenestration prevents high winds from tearing the leaves, or to help maximize the amount of rain that’s able to reach the plant’s roots, or as a defense mechanism to look less appealing to herbivorous creatures looking for a snack.
However, the leading theory about the purpose of fenestration suggests that Monsteras developed these holes as a way to improve lighting conditions for lower hanging leaves in the dense rainforests where they grow. This adaptation is not only useful, but also makes for a unique and visually striking plant. It’s no wonder they are so popular!
