Can Canna be a Water Plant?

Canna, also known as Canna lily, is a beautiful flowering plant that is popular for its large, tropical-looking leaves and striking blooms. While it is commonly grown in gardens and pots, there is some confusion about whether canna can also be a water plant. In this article, we will explore the characteristics of canna and its suitability for growing in water.

The Characteristics of Canna

Canna is a plant that is native to tropical regions of the Americas, including South America and Mexico. It belongs to the family Cannaceae and has several species, the most commonly cultivated of which is Canna indica. This plant is known for its large, broad leaves that can grow up to 2 meters in height, making it a popular ornamental plant for gardens and patios. The flowers of canna are also striking, with colors ranging from red and orange to yellow and pink. These blooms grow on long stems that can reach up to 1 meter in height, and they are favored by hummingbirds and other pollinators.

Canna as a Water Plant

While canna is not typically grown as a water plant, it is possible to grow it in water under certain conditions. Canna varieties that are grown as water plants are typically hybrids that have been developed specifically for this purpose. These plants are grown in aquatic containers, such as containers with drainage holes, floating rafts or aquatic pots, filled with a mix of potting soil and aquatic compost mix. They are placed in shallow water along the edge of a pond, lake or aquatic environment, so that the leaves and stems are partially submerged in water, while the roots are submerged. Canna as a water plant should be provided with enough sunlight, nutrients and oxygen to thrive, and should be protected from cold weather and frost damage.

The Pros and Cons of Growing Canna as a Water Plant

There are both advantages and disadvantages to growing canna as a water plant. On the positive side, canna can provide an interesting aesthetic feature in aquatic environments, and can be used to add color and texture to a pond or other water feature. Canna as a water plant can also be easier to maintain than other aquatic plants, as it is more tolerant of changing water conditions and can be grown in shallow water, eliminating the need for deep-water planting. However, growing canna as a water plant can also have negative impacts. The plant can grow aggressively in aquatic environments, quickly shading out other aquatic plants and disrupting the natural balance of the ecosystem. It may also attract pests and diseases that can damage other aquatic life forms, including fish and other aquatic animals.

The Bottom Line

While it is possible to grow canna as a water plant, it is important to consider the feasibility and implications of doing so. If you decide to grow canna as a water plant, it is important to choose a suitable variety, and follow proper planting and maintenance procedures. It is also essential to be aware of the potential negative impacts of growing canna in aquatic environments, and take measures to minimize these risks. Ultimately, whether canna can be a water plant depends on your goals, preferences, and the specific conditions of your aquatic environment.
