# Banana Plant and the Weird Looking Lily That Beginners Autumn in Love With I bought my first banana plant because it looked like nothing else in the shop and cost about the same as a sandwich. That was three years ago. I’ve now got one established in every tank I run, plus a few extras floating in takeaway containers on the kitchen windowsill waiting to develop proper root systems.
Sometimes the best aquascaping choices happen by accident. The thing that gets people about this plant is those ridiculous banana shaped tubers that give it its common name. They look like something a child would draw if you asked them to design an aquatic plant from memory.
But underneath that odd appearance is one of the most genuinely beginner friendly plants in the hobby, and I say that as someone who’s killed plenty of supposedly “easy” species through trial and error. | **Care Level** | **Lighting Needs** | **CO2 Required** | **Growth Rate** | **Max Size** | **Our Rating** | |—|—|—|—|—|—| | Very Easy | Low to Medium | No | Slow to Medium | 30cm | 4.5/5 | ## The American Native That Made It Big The banana plant, scientifically known as Nymphoides aquatica from the Menyanthaceae family (Wikipedia), comes from an interesting background for an aquarium staple. It’s native to the southeastern United States from Texas to Maryland (Wikipedia), which means it’s actually adapted to the kind of water conditions many of us have straight from the tap.
What’s particularly striking is that whilst this plant thrives in aquariums worldwide, it’s actually listed as an endangered species in the State of Maryland (Plants Rescue).
That disconnect between wild rarity and aquarium abundance tells you something about how well suited it is to tank life. Sometimes plants do better in our controlled environments than they’re managing in their natural habitats. The plant goes by several names beyond banana plant.
You’ll see it sold as banana lily, big floatingheart, and occasionally brain plant (Dustins Fish Tanks). The “brain plant” name comes from the wrinkled texture of those distinctive tubers, though I’ve always thought they look more like tiny yellow bananas than grey matter. It entered the aquarium trade relatively quietly compared to some plants, but it’s built a devoted following among hobbyists who appreciate plants that actually do what they claim to do.
In a hobby full of species that get called “beginner friendly” but then melt the moment you look at them wrong, the banana plant genuinely lives up to its easy-care reputation. ## What Makes This Plant Work So Well The secret to the banana plant’s success lies in those odd shaped tubers that make it look so distinctive. These banana shaped tubers are modified storage organs for nutrients (Dustins Fish Tanks), essentially built in energy reserves that let the plant survive conditions that would stress other species. It’s like having a plant that comes with its own battery pack.
This storage system means the banana plant can handle the inconsistencies that come with budget setups and beginner mistakes. Miss a week of fertilising? The tubers have got it covered.
Light a bit weaker than ideal? It’ll manage until you sort it out. Water parameters swing around a bit whilst you learn to manage a new tank?
The plant just rides it out. That resilience is worth its weight in gold when you’re starting out or working with basic equipment. The growth habit is what really sets it apart from other beginner plants though.
It can produce lily pad leaves at the surface and white flowers (FishLab), giving you options for how you want it to develop. Keep it trimmed back and it stays as an interesting midground accent with those distinctive heart shaped underwater leaves. Let it reach the surface and you get a completely different plant, with floating lily pads that create natural shading and occasionally reward you with small white flowers.
I’ve found the underwater leaves particularly rewarding in my smaller setups. They start as tight rosettes close to the substrate, then gradually spread upwards as the plant establishes. The leaves themselves are a fresh green colour with distinctive heart shapes that catch the light nicely.
In higher light conditions, the leaves are green above and dull purple below (Bantam Earth), which adds subtle colour variation without being flashy about it. The plant can grow up to 30cm or 12 inches tall (Bantam Earth), but it gets there gradually enough that you can shape how it develops. Unlike some fast growing species that can overwhelm a tank if you turn your back for a month, banana plants give you time to decide what you want from them.
What really impresses me is how it handles lower light conditions. No CO2 injection required and survives in low light (Buce Plant) isn’t just marketing speak with this one. I’ve got a banana plant thriving under a basic LED clip-on light in a 15 litre setup, producing steady new growth and maintaining healthy colour without any additional supplementation beyond basic liquid fertiliser.
The temperature requirements work well for most community tanks too. It prefers tropical temperatures between 68 to 82F (Aquarium Co-Op), which covers the range most of us run our heated tanks at anyway. No need to adjust your setup to accommodate this plant’s requirements. ## Where It Can Catch You Out The main mistake I see people make with banana plants is burying those distinctive tubers too deep.
The tubers should not be buried more than a quarter inch into substrate (Aquarium Co-Op). Bury them completely and they’re likely to rot before they can establish properly. I learned this the hard way with my first attempt, wondering why the plant was looking progressively worse despite seemingly perfect conditions.

The trick is to nestle them gently into the substrate so they’re stable but still mostly visible. Think of it like planting bulbs in a garden – you want them anchored but not smothered. Once the root system develops properly, they’ll hold themselves in place and you’ll see those distinctive yellow shapes peeking through your substrate.
Growth speed can be slower than expected, especially if you’re coming from faster species like hornwort or java moss. The banana plant takes its time establishing, particularly in lower light setups. This isn’t necessarily a problem, but it means you need patience rather than expecting instant results.
I usually tell people to give it at least two months before deciding whether it’s working in their particular tank. The plant can also be a bit fussy about major changes once it’s established. Move it to a completely different lighting setup or change your fertiliser routine dramatically, and it might sulk for a while before adapting.
It’s resilient, but it prefers gradual changes to sudden ones. If you let it reach the surface and develop lily pads, those floating leaves can create more shade than you might want for other plants below. It’s not necessarily a problem, but it’s something to factor into your overall plant selection and positioning.
I’ve found it works well towards the back or sides of smaller tanks where the shading effect actually helps create depth and contrast. ## Propagation That Actually Works One of the practical advantages of banana plants is how straightforward propagation is once you understand the process. The plant is propagated by cutting a mature lily pad leaf and floating it (FishLab), though you need to be selective about which leaves you use. I’ve had the best success taking leaves that have reached the surface and developed into proper lily pads.
Cut the stem close to where it joins the main plant, then float the leaf in a separate container or quiet area of your tank. Over several weeks, small plantlets will develop from the cut stem, eventually forming their own tiny tubers and root systems. The process requires patience rather than skill.
I keep the floating leaves in glass jars on the kitchen windowsill where they get decent light but stay out of the way. Room temperature water works fine, and you don’t need any special equipment or chemicals. Just change the water every few days to keep it fresh.
Once the new plantlets have developed proper tubers and a few leaves of their own, they can be planted like mature specimens. The success rate is surprisingly high if you’re patient enough to wait for proper development rather than rushing to plant them too early. This propagation method means you can expand your collection or share plants with other hobbyists without spending money on new specimens.
It’s also useful insurance – if something goes wrong with your main plant, you’ve got backups developing. ## Impact on the Hobby Scene The banana plant has carved out an interesting niche in aquascaping. It’s not the star of Instagram-worthy layouts or competition tanks, but it’s become a reliable background player in countless community setups. It’s the kind of plant that does its job quietly while other species get the attention.
For beginners especially, it often serves as proof that they can successfully grow aquatic plants. That confidence boost matters more than it might seem. I’ve watched people go from thinking they couldn’t keep anything alive to building complex planted tanks, and the banana plant is often somewhere in that journey as an early success.
The plant has also found a following among nano tank enthusiasts. In smaller setups where every plant choice matters, something that stays compact, grows predictably, and adds visual interest without demanding perfect conditions fills a valuable role.
It’s particularly popular in shrimp tanks where its steady growth provides grazing surfaces without creating maintenance headaches.
Its availability has remained consistently good over the years, unlike some plants that come and go with trends or supply issues. Most aquatic plant suppliers stock it regularly, and the price stays reasonable because it’s not seen as exotic or difficult to source. ## The Honest Verdict The banana plant earned its reputation as a beginner friendly species because it genuinely is one. Those distinctive tubers aren’t just visual novelty – they’re functional adaptation that makes the plant resilient enough to handle the learning curve that comes with planted tanks.
It’s not going to be the centrepiece of your aquascape, and it won’t give you the dramatic growth and colour changes you get from more demanding species. But it’ll be there consistently, adding subtle interest and proving that you can successfully maintain aquatic plants even with basic equipment and imperfect technique. For anyone working with budget constraints or limited space, it’s particularly valuable.
You don’t need CO2 systems, high end lighting, or complex fertiliser routines to keep it healthy and growing. A basic setup with regular water changes and occasional liquid fertiliser is enough to keep it thriving. I’d recommend it to anyone starting their first planted tank, setting up nano systems, or just wanting something reliable that looks a bit different from the usual suspects.
It’s forgiving enough for beginners but interesting enough that experienced aquascapers still find uses for it in their builds. See where this placed in our full ranking of beginner aquatic plants.
