Pothos and Philodendron are two popular houseplants that often confuse plant enthusiasts due to their similarities in appearance.
However, with a closer look, it becomes evident that these plants belong to different genera and possess distinct characteristics.
In this comprehensive guide, we will dive into the taxonomy, leaf shape, aerial roots, sheaths, and petioles of Pothos and Philodendron to help you easily differentiate between these two stunning plants.
Taxonomy: Understanding the Basics
Taxonomy, the science of naming and classifying organisms, provides us with a foundation to distinguish between Pothos and Philodendron.
While both are common names, Pothos belongs to the Epipremnum genus, and Philodendron belongs to the Philodendron genus.
Although they are related as members of the aroid plant family (Araceae), their genetic differences give rise to unique characteristics.
Shape of the Leaves: A Visual Clue
One of the easiest ways to differentiate between Pothos and Philodendron is by examining the shape of their leaves. Pothos leaves lack the pronounced curving and heart shape that are characteristic of Philodendron’s heart leaf.
By observing the widest part of the leaf, you can quickly determine whether you are dealing with a Pothos or a Philodendron.
Aerial Roots: Climbing Adaptations
Another distinguishing feature between Pothos and Philodendron is the appearance of their aerial roots. Aerial roots serve as climbers for these plants in their natural habitats.
Pothos exhibits wider and stubbier roots compared to the thinner aerial roots of Philodendron. As Pothos and Philodendron climb and mature, they develop larger foliage to support their growth.
Sheath: Philodendron’s Unique Trait
A notable characteristic of Philodendron is the presence of sheaths that emerge from the nodes where the leaf and petiole meet the vine.
These sheaths, also known as cataphylls, protect the plant as it grows and eventually turn brown and papery. In contrast, Pothos does not possess these sheaths.
By observing the presence or absence of sheaths, you can easily identify a Philodendron.

Petiole: A Tell-Tale Sign
The petiole, which joins the leaf to the vine, provides another clue to differentiate between Pothos and Philodendron.
The petiole of Philodendron is round and uniform, while Pothos exhibits an indentation and forms two brown, papery edges over time.
This distinction makes it effortless to identify whether you are dealing with a Pothos or a Philodendron.

- Philodendron ‘Moonlight’: A Philodendron cultivar with vibrant, yellow-green leaves.
- Philodendron ‘Xanadu’: A compact Philodendron variety with deeply lobed leaves.
Conclusion
In conclusion, although Pothos and Philodendron may share some similarities, their taxonomy, leaf shape, aerial roots, sheaths, and petioles can help us easily differentiate between the two.
By understanding these key characteristics, you can confidently identify whether you have a Pothos or a Philodendron in your plant collection.
So, go ahead and enjoy the beauty of these remarkable houseplants, knowing that you can tell them apart with precision.
