7 Aquarium Plants That Flower | With Tips and Pictures

Aquarium plants are a perfect, and natural, addition to your tank. They provide several key health benefits for aquarium water and create eye-popping visuals. With their wide range of shapes, sizes, and color, tank plants will suit any setup or aquarium design you have in mind. Still, do any of these water plants produce flowers? Aquarium Plants That Will Flower:

  • Madagascar lace (Aponogeton madagascariensis)

  • Anubias

  • Red tiger lotus

  • Bucephalandra

  • Aponogetons (above water)

  • Amazon Swords

  • Giant Hygro

Why Do Plants Flower We like to think of flowers in terms of their beauty. They decorate nature, our homes, and even our fish tanks. Still, flowers are more than ornamental fixtures, they are the reproductive organ of a plant. Petals, colors, and other eye-catching features are designed, by nature, to attract the eye of potential pollinators. All of this plays into the process of plant reproduction. When pollinated, flowers can create more seeds, which allows them to create more of their own kind. Growing this extra appendage is no easy task though. Plants require the right conditions, as well as, plenty of nutrition to flower and reproduce themselves. 1. Madagascar lace (Aponogeton madagascariensis) The first plant I will talk about is the Madagascar lace. This plant is known for its unique leaf structure and beautiful flowers. As its name suggests, the foliage of the Lace plant is delicate and lace-like. Its leaves have a skeletal appearance which makes them appear see-through. Flowers on the Lace have an equally distinct appearance and will blossom above the surface of your tank. Flowering this plant takes a moderate level of skill and a lot of work. Still, if you can provide the right water conditions, you can produce flowers on this plant in no time. To make the purple or white flowers of the Madagascar bloom, first adjust your water temperature. The temperature should be placed around 72 degrees to 82 degrees Fahrenheit with a water heater. Use your thermometer often to check that you have the right temperature range. And also make sure that your pH is around 6 to 7. In addition, your Madagascar lace will do better when it is rooted in your tank. You’ll want to pick a suitable substrate for it. Sand is good but a fine gravel might work better. The lights in your tank should be set on as well. Lace plants need moderate to high levels of light to thrive. Lastly, make sure you add enough nutrients to allow the plant to grow. This is crucial! For your Madagascar lace a combination of root tabs in the substrate with a liquid fertilizer is perfect. Also, adding CO2 make growing this plant a lot easier. I’ve seen people succeed without it, but most people do recommend CO2 with this plant. 2. Anubias Anubias are one of the few plants that can produce flowers while completely submerged. They are undemanding and have flexible needs. This makes them an ideal aquatic plant for new tank owners! I’ve had multiple Anubias flowers in my own aquarium. Unlike a lot of other flowering plants, Anubias can adapt to a range of temperatures and water conditions. They are hardy flora that are easy to flower. As a result of this, they are extremely popular with beginners who don’t have a lot of experience with planted tanks. The flowers of the Anubias are small and white. But can be bloomed in and out of your water. It just depends on how you want to grow your plant. Make sure to not bury the roots of this plant in substrate of any kind. Instead, attach the plant to a piece of wood or rocks. When the roots are buried, they will rot and the plant will die. Anubias don’t need a ton of light to survive, but if you want a bigger plant, more light can be used. Again, care depends on how big you want your plant to grow. Bigger Anubias require more fertilizer and extra light. But a smaller Anubias will only need lower levels of light to thrive. 3. Red tiger lotus If you want a large flower in your aquarium, the Red tiger lotus is an aquatic plant you’ll want to look into. The flower on the Tiger is big, white, and very low-maintenance! The pads of your plant should be kept above the water though. This way the flowers won’t wilt and die underwater. This plant can easily overtake your aquarium if you let it grow unchecked. Anchoring your plant with gravel should help curve some of its growth though. You can even hold back on fertilizer if you want to slow the growth of your Tiger lotus. Just keep an eye out on your plant for any signs of wilting. This video on Youtube shows an incredible timelapse of a flower or the red tiger lotus slowly growing out of the aquarium. Just amazing! The red tiger lotus is one of the few plants that I recommend buying online because the start as a tiny ball the size of small golfball. You can place this in your tank and the plant will start growing! 4. Bucephalandra While Tiger lotus will only grow flowers above water, Bucephalandra will grow flowers best submerged in water. These aquatic plants are compact and create small blooming flowers in your tank. Really, this is one of the simplest flowering plants to grow in a tank. You can give them any amount of light you want, and you can attach this plant to decorations or bury it in a substrate. Fertilization is optional for the Bucephalandra, because it’s a slow growing plant. If you want to promote optimal growth, I definitely recommend adding fertilizer. Keep this greenery in a temperature range of 71- 80 degrees. 5. Aponogeton Aponogetons are another great flowering plant for beginners. They are easy to care for and will produce flower buds on the surface of your tank water with minimal effort. Aponogetons grows in almost any condition and climate. They actually have an even larger temperature range than the Anubias and can be placed in water between 64 and 86 degrees Fahrenheit. However, make sure you have a big enough tank for your plant. Most Aponogetons will need twenty gallons at minimum to live in. They grow pretty big. Really, the only issue you might encounter with this plant is overgrowth. Aponogetons grow rapidly with very little care. So you’ll want to prune your plant often to keep it under control. Overall, the Aponogetons are large but simple plants that thrive in many tank setups. They are an ideal flowering plant!

6. Amazon Swords (Echinodorus grisebachii) Amazon Swords are a robust plant. They will grow in a number of aquarium conditions without issue. Temperature requirements are loose, so you can put your Amazon in waters anywhere from 60 degrees to 82 degrees. The adaptability of this plant is a plus, as you can fit this flora in with almost any kind of fish. However, know that the Amazon will not flower fast. It’s easy to take care of this plant, but it takes a long time to produce a flower from this species. To maximize your chances of flowering, give it plenty of light at high volumes. Amazon Swords need a lot of light, to begin with, so this won’t harm your plant. I would also recommend putting fertilizer and a good substrate in your tank for the best results. Rooting your plant is important. This way it can grow to its full potential. 7. Giant Hygro (Hygrophila corymbosa) Giant Hydro is the last flowering plant we will discuss in this list. The Hydro, also known as a Temple plant, requires straightforward care. It grows much faster than the Amazon Sword and has a colorful purple blossom which extends above the water. Luckily, it doesn’t take much to make this plant bloom. Just give it a moderate amount of light, and keep it in relatively warm water to maintain healthy growth. Water temperatures between 72 to 84 degrees is best for this plant. Fertilizer and CO2 can also be injected to speed up the flowering process. Hydro aren’t massive, but they do grow tall. Sometimes, they can grow up to two feet! Considering this, a taller tank with gravel is preferable for this species. The gravel will keep your plant well anchored as it grows upward towards the top of your aquarium! My Favorite Fishtank Products to Make Life Easier I am so happy you enjoy this post so far!

Click here Related Questions You might have additional questions about Aquarium plants that flower. I’ll talk about some other related information in this last section of the post. Many tank owners wonder how big their aquarium should be. At a minimum, you want a tank that is at least ten gallons. This will help your plant growth to its full height, and help flowers bloom on your plant. Some flora, like the Anubias, can survive in a smaller five-gallon tank. But personally, I think a bigger tank should be used. Another common question people ask is how long it takes for flowers to bloom. This depends entirely on the species of plant you have. Fertilizers, CO2, and proper water conditions can speed up the process though. So make sure you are taking care of your plant well if you want it to flower faster!

Underwater Pollination

Many species have flowers up and out of the water where there are far more pollen vectors.

Others rely on water currents and a little bit of chance. For aquatic plants whose flowers open under water, water pollination, or "hydrophily", has long been the only proposed mechanism.

Researchers also found that some marine invertebrates act as pollinators when the pollen sticks to their bodies and is deposited in female flowers.

How does pollination occur in aquatic plants like water hyacinth and water lily?

Since the water lily and water hyacinth are in the water but their stem part which is above the thalamus is not in the water. The pollen grains are in the upper part of thalamus so pollination can't done by water. That's y it is done by insects and wind. certain water plants like In Vallisneria the male flowers become detached and float on the surface of the water; the anthers are thus brought in contact with the stigmas of the female flowers. Surface hydrophily has been observed in several species of Potamogeton as well as some marine species.So the water helps in pollination too. HOPE THIS HELPS.
