A container water garden is a small, self-contained aquatic ecosystem that can be created in a container, such as a pot or a barrel, and is a great way to bring the beauty and tranquility of water into a limited space. These gardens are perfect for smaller outdoor areas like balconies, patios, or even indoor spaces.
When it comes to selecting plants for your container water garden, there are several factors to consider. The right combination of plants will not only enhance the aesthetics of your garden but also contribute to the overall health and balance of the ecosystem.
1. Floating Plants
Floating plants are an essential component of any water garden. These plants do not require soil and instead float freely on the surface of the water. They provide shade, reduce algae growth, and add a pop of color to the garden. Popular choices include:
- Water Lettuce (Pistia stratiotes): This plant forms rosettes of light green leaves and has long, dangling roots that help oxygenate the water.
- Water Hyacinth (Eichhornia crassipes): Known for its beautiful lavender flowers, this plant is an excellent choice for beginner gardeners as it is easy to grow and maintain.
- Frogbit (Hydrocharis morsus-ranae): A small, floating plant with heart-shaped leaves, frogbit is great for providing shade and shelter for small fish and other aquatic creatures.
2. Submerged Plants
Submerged plants are rooted in the soil at the bottom of the container and their leaves and flowers grow underwater. These plants are essential for maintaining water quality as they absorb nutrients that could otherwise cause algae bloom. Some popular choices include:
- Anacharis (Egeria densa): Also known as waterweed, anacharis helps to oxygenate the water, provides hiding places for fish, and absorbs excess nutrients.
- Hornwort (Ceratophyllum demersum): This bushy, dark green plant is excellent for reducing algae growth and provides cover for young fish.
- Water Violet (Hottonia palustris): With delicate flowers and submerged leaves, water violet adds an elegant touch to any container water garden.
3. Marginal Plants
Marginal plants grow along the edges of the container, with their roots submerged in water and their foliage above the water. These plants provide aesthetic appeal and also help in water filtration and creating a natural habitat for small animals. Some commonly used marginal plants include:
- Water Iris (Iris pseudacorus): This plant features vibrant yellow flowers and sturdy, upright foliage. It adds height and visual interest to the water garden.
- Pickerelweed (Pontederia cordata): With its long spikes of blue or purple flowers, pickerelweed is an excellent choice for attracting pollinators, such as bees and butterflies.
- Cattail (Typha): Cattails are known for their tall, cylindrical flower spikes and are often used for their architectural and ornamental value.
Remember that not all plants are suitable for container water gardens. Avoid using invasive species that can cause harm to the local ecosystem if they escape into natural water bodies. Also, consider the size of your container and choose plants that are proportionate.
In conclusion, selecting the right plants is crucial for the success of your container water garden. By combining floating, submerged, and marginal plants, you can create a harmonious and visually stunning aquatic ecosystem that will thrive and provide endless enjoyment.
