If you are new to collecting houseplants you may have come across the word fenestration. If you are wondering, what is fenestration in plants, we can help. Houseplants with fenestration are plants with holes or splits along or in their foliage.
Perforations or splits are often on plants of the monstera variety. The fenestrations are natural and are a part of the plants’ growing process. Another name for fenestrated leaves is split leaves or perforated leaves.

Frequently Asked Questions
Plants with split leaves or holes have what is known as fenestration. The fenestrations occur in plants when parts of the foliage cease to have cell growth. Botanists are still conflicted about why the plants do this. Particularly the monstera variety. Some claim it’s for filtering light and water. While others claim it’s for wind-related purposes.
Proper lighting is the key to encouraging leaf fenestration in plants. Bright filtered light is best for the plants. Low lighting can inhibit perforations or splits from occurring . Cebu Blue pothos typically only fenestrates if it climbs. Monstera delicosa may only start showing fenestration once they reach around 3ft or .9144m tall.
Double fenestration is when a plant, particularly monsteras, exhibits perforated holes and splits along the sides. You can encourage double fenestration through proper lighting, which is indirect but bright.
The holes in monstera leaves are fenestrations. They occur when cell growth dissipates in the part of the leaf. Botanists believe that plants with split leaves or holes have them to help filter water and light or combat wind damage.
A monstera plant may not fenestrate until reaching at least 3ft or .9144m in height. If your monstera plant continues to grow without fenestration, you may need to change its lighting environment. Bright but filtered lighting is best for the plant. Low or minimal lighting can inhibit the development of fenestrated leaves.
All monstera plants fenestrate. But it is important to note that many will not fenestrate until reaching a particular size or age. Many houseplant growers find that their monstera will not fenestrate until reaching 3ft or .9144m in height.
