Best Water-Loving Plants for Gravel Ponds without Soil

Gravel-bottomed ponds are a gardener’s dream. They offer a serene aquatic environment that doesn’t rely on traditional soil. The absence of soil means less mess and fewer pests. This creates a perfect setting for various water-loving plants. The beauty of these ponds lies not just in their aesthetic appeal but in their ability to support a thriving ecosystem.

Taro Plants (Colocasia esculenta)

Taro plants are a favorite among pond enthusiasts, and for good reason. Their large, heart-shaped leaves bring a touch of the tropics to any pond setting. These plants not only look stunning but also offer shade and shelter for fish and other aquatic life.

Size and Color Variations

Taro plants are available in different sizes and leaf sizes, which makes it easy for you to find the perfect fit for your pond. Some of the popular varieties include:

• Black Magic: This type of plant is famous for its dark, almost black leaves that provide a dramatic contrast to the pond landscape.
• Elephant Ear: This plant, with its huge leaves, is ideal for making a strong statement.
• Illustris: This plant has bright green leaves with purple veins, which adds an additional level of visual appeal.

You can mix and match different taro plants to create a dynamic and engaging pond environment because of these variations in height and color.

Lizard Tail Plants (Saururus cernuus)

Lizard Tail plants are a unique addition to any gravel-bottomed pond, known for their distinctive texture and fragrant white flowers. These plants thrive in the shallow edges of ponds, adding both visual and sensory appeal.

Where to Plant and How Much Sun is Needed

These plants like a bit of shade, so they’re perfect for ponds that are partly covered by trees or get indirect sunlight. If your pond is in full sun, you might want to plant Lizard Tail in a corner where it gets some shade, so it’s not in the intense midday sun.

Grassy Plants

Grassy plants are a flexible addition to gravel-bottomed ponds, providing height and texture. If you want to add some height to your gravel pond, consider planting Sweet Flag and Dwarf Papyrus.

• Sweet Flag (Acorus calamus): This plant is recognized for its sweet-smelling leaves and vertical growth, making it a great addition to the sides of ponds.
• Dwarf Papyrus (Cyperus haspan): This smaller plant has tufted stems and a fragile appearance, making it perfect for smaller ponds.

These grass-like plants are not only visually appealing, but they also serve a purpose, offering a habitat for pond animals and aiding in water filtration.

Considering Height Differences

When selecting grass-like plants for your pond, it’s important to think about their height. Sweet Flag, for example, can grow up to 24 inches tall, making it a good fit for larger ponds where its size can be fully appreciated. Dwarf Papyrus, on the other hand, usually grows to be about 12 to 18 inches tall, which makes it a better choice for smaller ponds or as a foreground plant in larger ponds.

Impatiens (Impatiens walleriana)

Impatiens are a vibrant, adaptable plant that loves shallow water, making them a lovely addition to any gravel pond. These plants bring color to the edge of the pond, with flowers ranging from soft pastels to bold, eye-catching colors.

Different Sizes and Non-Stop Flowering

Impatiens are available in many sizes, usually between 6 to 12 inches in height. This makes them a flexible choice for adding a splash of color to both small and large ponds. Their non-stop flowering habit guarantees that your pond stays lively and colorful from spring to fall.

Chameleon Plant (Houttuynia cordata ‘Chameleon’)

The Chameleon Plant is a fascinating and colorful plant that thrives in gravel-bottomed ponds. It is known for its patterned leaves and its ability to grow densely, adding a unique and lively touch to the edge of the pond.

The Chameleon Plant is a lovely but potentially invasive plant, so it needs to be carefully managed to stop it from taking over the other plants in the pond. But with a bit of TLC, it can be a beautiful and valuable addition to your pond.

Small Size with Big Impact

With a usual growth range between 6 to 12 inches, the Chameleon Plant is a great choice for those who want something easy to manage around the edges of their pond. The low growth of this plant allows it to fill in any gaps and create a full, carpeted look.

Nymphaea spp. (Water Lilies)

Water Lilies are a classic choice for any pond, known for their beautiful flowers and floating leaves that create a peaceful and scenic view. Not only are these plants visually appealing, but they also act as natural water filters, helping to maintain a balanced pond ecosystem.

How to Submerge Plants Properly

It is important to plant Water Lilies correctly for them to grow successfully. They need to be submerged in water between 12 and 18 inches deep. The tubers should be planted in containers filled with gravel. This will allow the roots to anchor themselves properly and give the plant the support it needs to grow.

Hippuris vulgaris (Mare’s Tail)

Mare’s Tail is a unique water-loving plant that stands out for its bottle-brush foliage and vertical growth. Its fine, whorled leaves look like a horse’s tail, adding a unique texture to the pond. Mare’s Tail is a flexible choice for both marginal and submerged planting, making it a great addition to any gravel pond.

How Tall They Grow and Their Preferred Environment

Depending on its environment, Mare’s Tail will usually grow to be about 6 to 12 inches taller than the surface of the water. It can handle anything from full sun to partial shade, so it’s a great choice for many different types of ponds.

Planting on the Edge vs. Underwater

Mare’s Tail is a versatile plant that can be placed either on the edge of the pond or underwater. This means you can use Mare’s Tail in many different ways, depending on your pond’s design and layout.

Inviting Plant Exploration

One of the most thrilling parts of gardening with gravel-bottomed ponds is the chance for exploration. With a wide array of plant species and varieties available, you can design a truly one-of-a-kind pond environment that showcases your personal style and tastes.
