39 Amazing Aquatic Flowers and Plants that Grow in Water
If you’re dealing with a wet garden, trying to establish a planted aquarium tank, or looking for some plants for your pond, you’ll want to look for aquatic plants. These plants can grow in fully submerged, floating on the water’s surface, or in constantly wet soil. We’ve rounded up a list of 39 amazing types of aquatic flowers and plants that you can try growing at home.
How Are Aquatic and Water Flowers Defined?
Aquatic and water flowers grow either in soil that is covered in water or in highly moist soil. That means they may grow in ponds, lakes, bogs, and beside streams and rivers.
People generally define aquatic plants by their growth habits.
- Submerged plants grow entirely underwater.
- Emergent plants have their roots in wet soil but grow out of the water.
- Floating plants float on top of the water, but their roots may grow below the water’s surface.
Can You Grow Aquatic Flowers and Plants at Home?
Each type of aquatic plant will have a preferred growing environment. Some plants can be submerged entirely, others grow best in shallow water, and some grow best in moist yet unsubmerged soil.
You may be able to grow these plants in garden ponds, aquariums, or naturally wet areas of your garden. You can also establish a water garden to support these plants.
Along with taking note of their preferred moisture level, you’ll also want to look at other environmental factors like sun and temperature. Some aquatic plants like full sun, while others can handle a bit of shade. Additionally, these plants’ temperature tolerances vary considerably.
39 Beautiful Types of Aquatic Flowers and Plants
1. Water Hyacinth (Pontederia crassipes)
Although the common water hyacinth is native to South America, it has now naturalized throughout much of the world. Water hyacinths can grow in freshwater between 50ºF and 90ºF. However, in many areas, it’s considered invasive.
The plant’s stem has hollow, buoyant nodules, which allow it to float on top of the water. The plant’s roots don’t attach to the soil but rather float in the water.
The plant also has glossy, thick, green leaves that can grow into dense mats and rise a few feet into the air. Purple flowers appear on long stalks.
2. Swamp Lily (Crinum americanum)
Swamp lilies spring up in moist areas or standing in freshwater in the Southeast United States. They have sword-like leaves arranged in small clumps and white lily-like flowers on the umbels.
