What Plants Grow on Water

Plants that grow on water, called hydrophytes, are typically found in wetlands, marshes, and swamps. They have adapted to live and thrive in wet environments, and are able to absorb nutrients and oxygen from the surrounding water. Let's take a closer look at some of the plants that can grow on water.

1. Water Lilies

Water lilies are one of the most recognizable aquatic plants. These plants float on the surface of still waters and have large, round leaves that can grow up to two feet in diameter. Their flowers are also stunning, and can be seen in shades of pink, yellow, white, and blue. Water lilies are not only beautiful, but they also provide critical habitat and food for fish and other aquatic animals.

2. Duckweed

Duckweed is a very small, free-floating aquatic plant that is found in ponds, lakes, and slow-moving rivers. They are less than 1/8 inch in length, and can multiply very quickly, covering large areas of water surface. It provides a crucial food source for many types of fish, and can also be used as a biofilter to help purify water.

3. Cattails

Cattails are tall, robust plants that are often found in marshes and swamps. They grow up to ten feet tall and have long, sword-like leaves that can reach up to four feet in length. Their flowers are dense cylinders of brown and green, and bloom in late summer. Cattails are used for erosion control, and are also a food source for many animals, including ducks and muskrats.

4. Taro

Taro is a low-growing aquatic plant that is often grown as a food crop in tropical regions. It has large, heart-shaped leaves that can grow up to three feet in length. The plant has an edible root that is often boiled, mashed, or fried, and is a staple food in many cultures. Taro is also used for medicinal purposes, and contains antioxidants that can benefit overall health.

5. Water Hyacinth

Water hyacinth is a fast-growing aquatic plant that is native to South America. It has lush, green leaves that can reach up to 12 inches in length, and produces beautiful lavender flowers. However, its quick growth and ability to spread rapidly make it an invasive species in many areas of the world. Water hyacinth can cause extensive damage to aquatic ecosystems by choking out native species and blocking sunlight from reaching the water.

Conclusion

Plants that grow on water are incredibly diverse and important to aquatic ecosystems. They provide habitats and food sources for many animals, and also play a crucial role in water filtration and purification. However, non-native species like water hyacinth can disrupt these ecosystems and cause extensive damage. It's important to understand the impact of introducing new plants to an environment, and take steps to prevent the spread of invasive species.
