We’ll also walk through a complete care guide for both, tackle common problems you might face, and explore the amazing benefits of bringing these green giants into your life. Let’s solve this plant mystery together!

The Great Impostor: Unmasking the “Split-Leaf Philodendron”

Before we dive into a side-by-side comparison, let’s clear up the biggest source of confusion right away. The plant most people call a “split-leaf philodendron” and see sold under that name is actually a Monstera deliciosa.

Yes, you read that right! Due to its split leaves, the Monstera was mistakenly lumped in with the Philodendron family ages ago, and the nickname stuck. It’s a classic case of mistaken identity that has trickled down through generations of gardeners. So, when you see a vining plant with leaf holes and splits at your local garden center labeled “split-leaf philodendron,” you are almost certainly looking at a Monstera.

To make things even more interesting, there is a true “split-leaf philodendron,” but it’s a completely different plant called Thaumatophyllum bipinnatifidum. Until recently, it was classified as Philodendron selloum or Philodendron bipinnatifidum, which is why it holds the philodendron name. This plant has deeply lobed leaves but a very different growth style. For clarity in this guide, when we say “split-leaf philodendron,” we’ll be referring to this true variety, the Thaumatophyllum.

Monstera Deliciosa vs Split Leaf Philodendron: A Head-to-Head Comparison Guide

Now that we’ve cleared the air, let’s get down to the fun part. Learning how to monstera deliciosa vs split leaf philodendron is all about training your eye to spot a few key characteristics. Once you know what to look for, you’ll never be fooled again.

Leaf Shape and Fenestrations (The Telltale Sign!)

The most obvious difference lies in the leaves. This is your number one clue!

  • Monstera Deliciosa: Young Monstera leaves are solid and heart-shaped. As the plant matures and gets enough light, it develops splits from the edge of the leaf inward. More importantly, it also develops fenestrations—which are holes that form in the middle of the leaf, completely enclosed like little windows. These holes are the key identifier for a Monstera.

  • Thaumatophyllum bipinnatifidum (True Split-Leaf): This plant’s leaves are also deeply lobed, but the splits always start at the leaf’s edge and cut inward. It does not develop the characteristic enclosed holes (fenestrations) that Monsteras do. Its leaves also tend to have a more frilly, ruffled, or wavy appearance along the lobes.

Growth Habits and Size

How the plant grows is another dead giveaway. Think “climber” versus “shrub.”

  • Monstera Deliciosa: This is a true climbing vine. In the wild, it uses its long, brown aerial roots to cling to trees and climb toward the light. In your home, it will want to do the same! It needs a moss pole or trellis for support to grow upright and develop those beautiful, mature leaves. Without support, it will trail and spread horizontally.

  • Thaumatophyllum bipinnatifidum (True Split-Leaf): This plant is an upright grower but not a climber. It forms a thick, woody, trunk-like stem as it ages. It grows more like a tree or a self-supporting shrub, creating a wide, dramatic canopy of leaves. It doesn’t produce the long, vining stems that a Monstera does.

Stems and Petioles (A Subtle Clue for the Pros)

If you want to get really granular, look at where the leaf meets the stem.

  • Monstera Deliciosa: Look closely at the top of the petiole (the little stalk that connects the leaf to the main stem). You’ll find a small, wrinkled, elbow-like joint called a geniculum. This amazing feature allows the leaf to rotate and orient itself toward a light source, like a little satellite dish. It’s a hallmark of the Monstera genus.

  • Thaumatophyllum bipinnatifidum (True Split-Leaf): This plant does not have a geniculum. The petiole is smooth from the main stem all the way to the leaf. As old leaves die and fall off its trunk, they leave behind cool, eye-shaped scars that give the trunk a unique pattern.

The Ultimate Monstera Deliciosa vs Split Leaf Philodendron Care Guide

The great news is that both of these plants have very similar care requirements. They are both relatively easygoing tropicals, perfect for adding a jungle vibe to your home. Following these monstera deliciosa vs split leaf philodendron best practices will set you up for success.

Light Requirements

Both plants thrive in bright, indirect light. Think of a spot near an east-facing window or a few feet back from a south or west-facing window. Too much direct sun will scorch their leaves, leaving brown, crispy patches. Too little light, and the Monstera may not develop its signature splits, while the Thaumatophyllum may become leggy.

Watering Best Practices

Overwatering is the fastest way to harm these beauties. A good rule of thumb is to water thoroughly when the top 2-3 inches of soil feel dry to the touch. Let the excess water drain completely from the bottom of the pot. In the winter, you’ll likely need to reduce your watering frequency as the plant’s growth slows down.

Soil and Fertilization

Both plants need a chunky, airy, and well-draining soil mix. A standard potting mix amended with perlite, orchid bark, and coco coir is perfect. This mimics the forest floor environment they’re used to. Feed them with a balanced liquid fertilizer diluted to half-strength every 4-6 weeks during the spring and summer growing season.

Humidity and Temperature

As tropical natives, they adore high humidity! Aim for 50-60% humidity if you can. You can easily boost humidity by grouping plants together, placing them near a humidifier, or setting them on a pebble tray with water. They prefer standard indoor temperatures between 65-85°F (18-29°C).

Common Problems with Monstera Deliciosa vs Split Leaf Philodendron

Even the most experienced gardener runs into issues sometimes. Here are some of the most common problems with monstera deliciosa vs split leaf philodendron and how to solve them with some sustainable tips.

Why Aren’t My Monstera Leaves Splitting?

This is the number one question from Monstera parents! The answer is almost always a combination of two things: age and light. A young Monstera will only have solid, heart-shaped leaves. It needs to reach a certain level of maturity before it has the energy to produce fenestrations. To encourage splits, give your plant more bright, indirect light and be patient!

Dealing with Yellowing Leaves

Yellowing leaves are typically a sign of overwatering. The soil is staying too soggy, and the roots can’t breathe. Before you water, always check the soil with your finger. If it’s still damp, wait a few more days. Ensure your pot has good drainage holes to let excess water escape.

Frequently Asked Questions About Monstera Deliciosa vs Split Leaf Philodendron

Is a split-leaf philodendron actually a Monstera?

In most cases, yes! The plant commonly sold in stores as a “split-leaf philodendron” is almost always a Monstera deliciosa. The true split-leaf philodendron, Thaumatophyllum bipinnatifidum, is a different plant that doesn’t vine and doesn’t have leaf holes (fenestrations).

Which one is easier for beginners?

Both are fantastic and forgiving plants for beginners! If we had to choose, the Monstera deliciosa might be slightly easier simply because its care is so widely documented online. Its vining nature is also easy to support with a simple moss pole. Both are very resilient choices, so you can’t go wrong.

Can I grow these plants outside?

Yes, but only if you live in a suitable climate. Both plants are native to tropical regions and can be grown outdoors year-round in USDA hardiness zones 10-12. In colder climates, they can be enjoyed outdoors during the summer and brought inside before the first frost.

How can I encourage more splits and holes in my Monstera’s leaves?

The key is giving it more bright, indirect light! Light is the energy source for a plant, and producing complex split leaves takes a lot of energy. Providing a moss pole for it to climb can also signal to the plant that it’s mature and stable enough to produce its iconic adult leaves.

The Choice is Yours!

So there you have it—the mystery is solved! The great monstera deliciosa vs split leaf philodendron debate really comes down to spotting a few key details: holes in the leaves, a vining habit, and that little “knee” joint called the geniculum all point to the beloved Monstera deliciosa.
