I’m here to tell you that it probably wasn’t your fault. The truth is, many stores sell terrestrial or semi-aquatic plants right alongside true aquatic ones, leading to confusion and disappointment. You’ve probably asked yourself, are terrarium plants real, and if so, why are they being sold for my aquarium?

So, Are Terrarium Plants Real? Unpacking the Core Confusion
Let’s get the biggest question out of the way first. Yes, absolutely! Terrarium plants are very real, living plants. They aren’t plastic or fake. The problem isn’t their reality; it’s their intended environment.
Think of it like this: a polar bear is a real animal, but you wouldn’t expect it to thrive in the Sahara Desert. Terrarium plants are the polar bears of the plant world when it comes to being fully submerged in an aquarium.
These plants are scientifically known as terrestrial or marginal plants. They are adapted to grow on land in high-humidity environments (like a terrarium or a rainforest floor) or along the banks of rivers and bogs with their roots in the water but their leaves in the air. They simply don’t have the biological equipment to “breathe” and perform photosynthesis completely underwater. When you submerge them, they essentially begin to drown, very slowly.
This is the central point of our are terrarium plants real guide: understanding that a plant’s reality isn’t the issue, but its compatibility with a fully aquatic life is.
Why Your Local Pet Store Sells Non-Aquatic Plants
It seems counterintuitive, right? Why would a store dedicated to aquatic life sell plants that are destined to fail in an aquarium? There are a few practical, business-driven reasons.
First, many of these terrestrial plants are incredibly vibrant and colorful. Think of the striking white veins on a Fittonia (Nerve Plant) or the deep purple of a Hemigraphis (Purple Waffle). These colors are an easy sell, especially to newcomers who want to add a pop of color to their tank instantly.
Second, they are often hardier (out of water) and easier to farm in massive quantities than true aquatic plants. They can be grown quickly and cheaply in greenhouses, packaged in those plastic tubes you often see, and shipped with a low rate of loss. This makes them a more profitable product.
Finally, there can be a simple lack of specialized knowledge. The person stocking the shelves might not be a seasoned aquascaper. They just know they have a box of “aquarium plants” to put out. This is why it’s so important for you, the aquarist, to be the expert and protect your own tank.
The “Do Not Submerge” List: Common Problems with Are Terrarium Plants Real
Knowledge is your best defense. Getting familiar with the usual suspects will save you money and protect your aquarium’s delicate ecosystem from the ammonia spike that comes from a decaying plant. Here are some of the most common non-aquatic plants often sold for aquariums.
If you see these, admire their beauty, but leave them for a terrarium project!
- Dracaena sanderiana (Lucky Bamboo): This is probably the number one offender. Its stalks will rot from the bottom up when fully submerged, fouling your water.
- Spathiphyllum wallisii (Peace Lily): Those beautiful white-veined leaves are a dead giveaway. They are bog plants that need their leaves in the air.
- Syngonium podophyllum (Arrowhead Plant): A classic houseplant. It will quickly turn to yellow mush underwater.
- Ophiopogon japonicus (Mondo Grass): This looks like a lush aquatic grass, but it’s a terrestrial plant used in landscaping. It will survive for a while before slowly dying off.
- Hemigraphis colorata (Purple Waffle): Its stunning purple underside is tempting, but this plant cannot survive underwater and will decay rapidly.
- Fittonia sp. (Nerve Plant): The intricate, colorful veins on its leaves are a clear sign it’s meant for a terrarium, not an aquarium.
- Chlorophytum comosum (Spider Plant): Sometimes sold in its smaller forms, this popular houseplant will not adapt to life below the surface.
Remember, the most common problems with are terrarium plants real stem from this simple incompatibility. They rot, release ammonia, and can crash your cycle, endangering your fish.
The Paludarium Solution: Are Terrarium Plants Real Best Practices
Now for the fun part! Just because you can’t submerge these plants doesn’t mean you can’t use them at all. This is where you can get really creative and embrace some advanced, yet easy, aquascaping techniques.
The secret is emersed growth. This is a fancy term for having the plant’s roots in the water while its leaves and stems grow up into the open air. This is how many of these plants live in nature!
How to Achieve Emersed Growth:
- Hang-on-Back (HOB) Filters: This is one of the easiest methods. You can simply tuck the roots of a plant like Pothos or a Peace Lily into the media compartment of your HOB filter. The flowing water provides tons of nutrients, and the plant will thrive.
- Suction Cup Planters: You can find small plastic baskets with suction cups that stick to the inside of your aquarium glass. Plant a small terrestrial plant in one of these right at the waterline for a beautiful effect.
- Custom Hardscape: Create a scape with driftwood or rockwork that extends above the water’s surface. You can wedge plants into the crevices, allowing their roots to trail down into the water.
- Paludariums: For the truly ambitious, a paludarium is a setup that is part aquarium, part terrarium. These dedicated tanks are perfect for showcasing marginal plants in their natural state.
Following these are terrarium plants real best practices allows you to use these beautiful plants safely and effectively, creating a truly unique and lush environment.
Benefits of Are Terrarium Plants Real When Used Correctly
When you use these plants for emersed growth, you unlock some incredible benefits for your aquarium’s ecosystem. It’s a perfect example of a sustainable are terrarium plants real approach that works with nature, not against it.
Here are the top advantages:
- Superior Nitrate Removal: Terrestrial plants growing with their leaves in the air are absolute powerhouses at consuming nitrates. Because they have unlimited access to CO2 from the air, their growth isn’t limited like it is for submerged plants. They will act as a super-powered natural filter, keeping your water pristine.
- Aesthetic Dimension: Growing plants out of the top of your tank adds a whole new layer of depth and beauty to your setup. It bridges the gap between the underwater world and the room it’s in, creating a stunning, jungle-like focal point.
- Provides Shelter: The dangling roots and overhanging leaves create a natural, shaded canopy. This is perfect for fish like bettas, gouramis, and killifish that appreciate cover and calmer surface areas.
- Eco-Friendly Aquascaping: By using plants this way, you’re creating a more balanced and self-sufficient ecosystem. The plants purify the water, which means a healthier environment for your fish and potentially fewer water changes for you. This is the heart of an eco-friendly are terrarium plants real setup.
Your Are Terrarium Plants Real Care Guide: How to Spot an Imposter
Okay, you’re in the store, faced with a wall of green. How do you tell the real deal from the land-lubbers? Don’t worry, I’ve got you covered. Here is a simple checklist to run through.
The In-Store Identification Checklist:
- Feel the Leaves: Gently touch a leaf. Is it thick, waxy, or stiff like a typical houseplant? That’s a huge red flag. True fully aquatic plants often have leaves that are more delicate, thinner, or even translucent, designed for efficient nutrient absorption from water.
- Check the Name: Does the name sound like a garden plant? “Mondo Grass,” “Peace Lily,” “Lucky Bamboo,” or “Arrowhead Plant” are big clues. When in doubt, pull out your phone. A 30-second Google search of the plant’s name followed by “aquatic” will give you an instant answer.
- Look at the Colors: While there are colorful aquatic plants (like some Alternanthera species), be very suspicious of plants with bold, painted-on looking patterns, like bright pink splotches or stark white veins. These are often characteristic of terrestrial plants bred for ornamental appeal.
- Examine the Roots: Many non-aquatic plants are sold with a dense, soil-like root ball wrapped in foam or a small pot. True aquatic plants are more often sold as bare-root bunches or with much finer, more delicate root systems.
This simple are terrarium plants real care guide is your best tool. Trust your instincts, and never be afraid to use your phone to become the most informed shopper in the aisle.
Frequently Asked Questions About Are Terrarium Plants Real
What happens if I put a terrarium plant fully underwater?
Initially, it might look fine. But within a few weeks to a couple of months, it will begin to decay. The leaves will become translucent, the stems will get mushy, and the roots will rot. This decomposition releases ammonia and other toxins into your water, which can harm or even kill your fish, especially in a smaller aquarium.
Are moss balls terrarium plants?
Great question! No, Marimo Moss Balls are not terrarium plants. They are a unique species of filamentous green algae (Aegagropila linnaei) that are 100% aquatic. They are an excellent, beginner-friendly, and completely safe addition to any aquarium.
Can I use Pothos in my aquarium?
Yes, and you absolutely should! Pothos (Epipremnum aureum) is the poster child for using terrestrial plants correctly in an aquarium. Just let its roots dangle in the water from the top of the tank (draped over the side or tucked into a filter) and keep its leaves in the air. It is one of the best nitrate-absorbing plants you can find!
How long will a non-aquatic plant survive submerged?
This varies greatly depending on the species. A tough plant like Lucky Bamboo might last for several months before showing serious signs of rot. A more delicate plant like a Fittonia might start to melt in just a couple of weeks. Regardless of the timeline, the outcome is always the same: eventual decay and a negative impact on your water quality.
Conclusion: Go Forth and Grow with Confidence!
The question “are terrarium plants real” isn’t about whether they are living things, but whether they can live in your underwater world. Now you know the answer: most cannot survive fully submerged, but they can be incredible additions when used correctly.
You are no longer at the mercy of confusing store labels. You have the knowledge to identify the imposters, protect your aquarium from decaying plants, and even experiment with emersed growth to create a healthier, more beautiful, and sustainable ecosystem.
So the next time you’re plant shopping, walk in with confidence. You’ve got this! You know how to choose plants that will not just survive, but truly thrive. Happy scaping!
