Today, I’m going to talk about why some plants have fenestrations on their foliage. Fenestrations refer to splits and holes in the leaves of certain plants, which are a fascinating and beautiful natural feature. You can see these fenestrations on popular houseplants like Monstera deliciosa and Alocasia, as shown here. These openings make the plants very eye-catching, with beautiful slits and even small fenestrations along the midrib.
The word “fenestration” comes from the Latin word fenestratus, meaning “provided with openings.” These openings play a critical role in the plants’ native habitats. Here are some benefits:
- Light Penetration: Fenestrations allow more light to reach lower leaves, especially in the dense tropical rainforest where light is limited.
- Airflow: The splits improve airflow, which helps the plants breathe, withstand high winds, and avoid fungal diseases.
- Water Filtering: The openings help water reach the plant’s roots more effectively.
- Camouflage: The holes can deter grazing animals by making the plant appear eaten or unappealing.
While these adaptations are essential in their natural habitats, fenestrations aren’t as critical indoors. Instead, they make these plants highly desirable for their unique and stunning appearance.
This Alocasia and Monstera deliciosa come from Costa Farms, and I’ll include a link below for how to get them.
