What is Philodendron McDowell?

The full name of this plant is Philodendron Dean McDowell. So, when you hear this particular name, it sounds pretty unusual for a plant name. It is named after a person.

The botanist who created this hybrid plant named it after his friend. This Philodendron is new to the botanical world, as it was created in the late 1980s.

This Philo is highly praised for its large deep green leaves. The leaves have the well-known heart-shaped style commonly found in the rest of the Philodendrons.

The native area of this plant is South American tropical forests. So, it is easily found in Colombia, Peru, and Brazil. This plant is not entirely an epiphytic, as it grows parallel to the ground.

What is Philodendron Pastazanum?

Philodendron Pastazanum is commonly known as the pasta plant. It got its name from its original exploration place, first found in Ecuador, particularly in the province of Pastaza. 

This plant looks much like its hybrid but has slightly smaller leaves. The pasta plant has fleshy stalks that make it not a climber. It falls into the category of creeping plants.

Just like many other philodendrons, this pasta plant has big cordate leaves. This plant features evergreen foliage.

The midrib of the leaves has a very light shade that contrasts with the dark green foliage. The leaves of Philodendron Pastazanum are shiny and textured.

Caring for this plant is easy. So anyone can be a good parent to this plant, even the busy and forgetful type. It loves humidity and warmness.

It also requires indirect exposure to bright sunlight. However, it can tolerate a poorly lit area. Keep in mind that poor lighting can stall its growth.

6. Petiole markings

Taking an in-depth look at the petioles of each plant can indicate the difference in their formation. The petioles of the Dean McDowell plant have tiny red markings that give these petioles their texture.
