What Are Aquatic Plants?

Water plants or aquatic plants can grow in a water body, either saltwater or tap water. They are primarily present in wetlands water bodies like ponds and lakes. You might not recognize a water plant immediately as they have their roots submerged in water. 

Aquatic plants can be classified as:

  1. Deep Floaters- These plants float freely inside the water body. They don’t have roots attached to even the soil at the bed of the water body. These include such as hydrillas and bog moss. 
  2. Free Floaters- These plants also don’t have their roots attached to the waterbed, but they don’t float inside the body. They can float freely only on the surface of the body while their roots absorb water. So, you can spot them from the outside.
  3. Rooted- The roots of these plants are attached to the bed soil, but some parts float freely on the surface. They need sunlight to float on the surface. Some examples are knotweed and redroot.
  4. Algae- These are the oldest aquatic plants known and popularly found in the oceans. They are small in size and have no leaves or stems. Some examples include lyngbya and musk grass. 

In the large water bodies, these plants help sustain marine life by acting as food for the organisms. At home, you can plant these in a pond or a water garden or an aquarium or even in jars and bottles. All they need is water and a little maintenance. 

Why Do You Need Indoor Water Plants?

Besides being an aesthetic pleasure to the eyes and even nose, indoor plants that grow in water have numerous benefits. Most of these plants can get transferred into garden soil which serves a dual purpose. They always turn out to be a center of attraction.

2. It Occupies Lesser Area

Aquatic plants can grow even in a glass of water. If you directly submerge a carrot in a glass jar full of water for some days, it will start thriving. They do not occupy much area and can be stored as per requirements.

If you don’t have a garden area, or a large area to keep pots full of soil, indoor plants are your solution. Simply fill a jar of water and put the seed or the plant. You can even buy adhesive jars which simply stick to the doors or windows and can be filled with water.

3. Fewer Pests Infect It

Soil provides inhabitable conditions to most pests, insects, and fungi. They are very irritating, and removing them is a cumbersome task. Soil plants need regular care and still end up being affected by fungi, pests, or even caterpillars.

Plants that grow in water do not face this problem at all. There is no hassle of pests in water. Simply changing the water over some days or even weekly avoids all problems. The plant also remains relatively healthier for a longer period if not given proper attention.

Sweet potato vine is an herbaceous perennial tropical plant native to North America. It is widely cultivated in large parts of America and counts as a major food crop in the southern United States, tropical America, and the Caribbean. They grow best when planted during spring and are not desirable to grow during winters. Sweet potato vine belongs to the same species family as edible sweet potatoes. They are yielded mainly for their leaves more than for their edible tubers. 

Sweet potato vines are both outdoor and indoor plants. It produces heart-shaped leaves, tubers which can be found in variable shapes and colors. Like many other plants, sweet potato also needs regular care to keep them in appropriate condition. 

The sweet potato vine can be grown from a tuber or cutting. The tuber and cutting are put into a vase and allowed to grow. While pruning the plant makes sure the tools are alcohol wiped to eliminate the spread of pest and diseases. The plants grow on for several years, and the water should be frequently changed to discourage bacteria from growing. 

2. Wandering Jew

The Inch or Tradescantia zebrine, also known as the Wandering Jew, traditionally is an easy, fast-growing plant native to tropical regions of America. It has heart-shaped green leaves with purple strips over them. It adds wonderful colors to the container port in the garden with its vibrant foliage that will trail or spread across walls or hanging planters.

The most common Wandering Jew species grown as houseplants are Tradescantia zebrina, Tradescantia fluminensis, and Tradescantia pallid. These plants cannot tolerate cold weather conditions and thus thrive best as indoor houseplants. 

To grow and care for the Wandering Jew may be a bit demanding, but with proper lighting, watering, and temperature, it will be a great addition to your room corner. To grow Wandering Jew, choose a wide-spaced container, and submerge the stem cutting of approximately 6 inches into the water. Make sure to cut the leaves from the bottom of all stem cuttings. The new roots will start to form within one to two weeks of planting. 

Wandering Jew needs medium to full, indirect sunlight to grow. Direct light fades the color of its leaves. Remove the discolored leaves as and when required. Wandering Jew should be fertilized with a water-soluble fertilizer diluted to half-strength as it starts producing new growth. You may also re-pot it into a new container if the root systems have grown fully inside the pot. Ensure the container vase is large as it is fast-growing and may require repotting during spring.

3. Spider Plant

The plantlets or spirderettes, as these are known, are submerged into the water container. Make sure only the lower part of the cutting is submerged. You can see the plant developing in one to two weeks from planting. 

The plant thrives best in the morning sunlight and thereafter indirect sunlight during the daytime. You will need to keep frequently changing the water, once every 5 to 7 days, to avoid leaves turning brown.

Now that we know about the best indoor aquatic plants, let us discuss some basic tips to care about these beautiful creatures at your home. If you keep the following tips in mind, you will have a full blooming indoor water garden in no time, thanks to these plants!

1. Containers

Although you can grow these plants in any waterproof bottles or vases, yet when considering house décor, using the appropriate container makes a difference. Also, containers impact the growth and spread of the plant to some extent. You can even change the bottle if the plant outgrows it or if it collects dirt.

There are a wide variety of containers used in a water garden, like jars, test tubes, chipped glasses, vessels, or wall vases. With a little creativity of your own, you can create a beautiful water garden in your home. As these plants do not need direct sunlight, these containers can be placed at any place you choose around the house.

2. Changing Water

The only important care aquatic plants require is regular changing of water. No wonder they are low maintenance. On some days, as the plants use the water minerals and excrete in it, the water starts to look dirty. It starts appearing cloudy. This is the indication that water changes are required.

Keeping the plant in dirty water for long can lead to algae formation and might even kill the plant. The water evaporates too, so keep putting some water as and when you see the jar a little empty. 

3. Liquid Fertilizer

There is no special type of fungicides or pesticides for plants that grow in water as they do not often face these problems. Still, one problem they might face is the formation of algae. Although the choice of the jar works a lot in preventing algae, regularly cleaning the water is also necessary.

Further, you can use mild liquid fertilizers sometimes. These are not very strong and help boost the growth of the plant along with keeping them healthy.

4. Propagation

Propagation refers to the act of transplanting the water plant into the soil. Generally, when the plant develops roots, it is planted properly into the ground or in garden pots with soil. Some people grow plants, like herbs, in water for propagation only.

Even when the plant overgrows the jars and is too large to be kept inside, it can be propagated. Plants are like your babies, and you might not always want to cut them or trim them, so you can choose to transplant them properly in the ground.
