14 Beautiful Purple Water Plants to Transform Your Space

1. Nymphaea ‘Atropurpurea’ (Hardy Purple Water Lily)

The hardy purple water lily is a classic aquatic plant with deep, dramatic blooms that float elegantly on the water surface. Hardy and low-maintenance, it thrives in larger ponds or containers and can bloom from early summer into fall. Its round, floating leaves provide shade to the water below, reducing algae growth while supporting aquatic life.

2. Violet Water Lily (Nymphaea)

Similar to its hardy cousin, the violet water lily produces vivid violet flowers that instantly draw attention. Ideal for decorative ponds and water gardens, its blooms create an eye-catching contrast against the green lily pads. It thrives in full sun and requires shallow water with nutrient-rich soil for optimal growth.

3. Hottonia palustris (Water Violet)

Known as featherfoil or water violet, this submerged plant adds delicate texture with its feathery foliage. Small purple blossoms emerge from the tips of the stems, making it ideal for quieter areas of a pond. It’s an excellent choice for naturalistic pond designs, providing both aesthetic appeal and ecological value.

4. Iris ensata (Japanese Water Iris)

The Japanese water iris is highly prized for its striking violet blooms and tall, architectural form. Often used at the edges of ponds or water features, it offers vertical interest while thriving in shallow water or wet soil. The lush green foliage complements its purple flowers, creating a striking focal point in any garden setting.

5. Pontederia cordata (Pickerel Weed)

This marginal plant is celebrated for its spikes of violet-blue flowers. Not only does it add height and color to your pond edges, but it also attracts butterflies and beneficial insects. Pickerel weed thrives in wet soil and shallow water, making it a versatile option for both natural and designed water gardens.

6. Water Forget-Me-Not (Myosotis palustris)

The delicate water forget-me-not features tiny purple flowers that form dense clusters along pond edges. This plant provides excellent ground cover for wet areas and creates a soft, romantic feel in the garden. It’s perfect for layering with taller plants for a lush, multi-dimensional effect.

7. Alternanthera reineckii “Lilacina”

For aquarium enthusiasts or indoor water features, Alternanthera reineckii offers a bold splash of purple color. Its vibrant, reddish-purple stems and leaves bring a striking contrast to green aquatic plants. It grows well as a foreground or midground plant, adding depth and texture to submerged landscapes.

8. Alternanthera sessilis “Purple”

Compact and versatile, Alternanthera sessilis is ideal for smaller water containers or ponds. Its purple foliage adds consistent color and can tolerate partial submersion, making it an excellent choice for low-maintenance aquatic planting schemes.

9. Utricularia purpurea (Purple-Flowered Bladderwort)

A fascinating and somewhat unusual aquatic plant, the purple-flowered bladderwort produces tiny violet blossoms above the water while capturing small insects underwater to supplement its nutrients. It thrives in shallow waters and is an exciting addition for gardeners seeking an interesting and educational plant.

10. Hygrophila corymbosa (Purple-Flowered Temple Plant)

This versatile plant grows submerged or partially above water and blooms with purple flowers in humid conditions. Known for its rapid growth, it can be used to fill empty spaces in ponds or aquariums quickly, while the blooms add seasonal beauty.

11. Lilac Lotus and Water Lotus Cultivars

Many water lotus hybrids showcase shades of purple or lavender, offering a spectacular focal point in larger water features. Though they require deeper water and ample sunlight, the stunning blooms and broad leaves create a luxurious centerpiece that elevates any pond or water garden.

12. Purple Pickerel Plants (Various Cultivars)

Multiple pickerel weed cultivars display violet hues and thrive in wet soils or shallow water. These cultivars provide vertical interest and seasonal bloom cycles that extend the visual appeal of your aquatic landscape.

13. Purple Floating Marginal Plants (Seasonal Varieties)

Various seasonal floating or marginal plants bloom in purple shades during spring and summer. These plants are easy to incorporate and can be rotated seasonally to maintain a vibrant water feature throughout the year.

14. Aquatic Bulbs With Purple Blooms (Mixed Collections)

Aquatic bulbs, including water irises and lilies, often include purple-flowered species. Planting these bulbs in shallow pond beds can create splashy, seasonal color, adding variety and interest to your aquatic design.


Design Ideas to Maximize Impact

Layered Planting

Layering different heights and textures ensures that your water garden feels full and dynamic. Place taller plants like Japanese water iris and pickerel weed toward the back or edges, while shorter or floating plants such as purple water lilies or water forget-me-nots occupy the foreground.

Floating Displays

Floating plants, including water lilies, create mesmerizing patterns on the water surface. Arrange them in clusters or patterns to mimic natural ponds or create symmetrical designs for a more formal water feature.

Edge Accents

Marginal plants like iris, pickerel weed, and water violet provide a soft boundary around your pond while adding splashes of purple. These plants also help stabilize soil at pond edges and create habitats for beneficial insects.

Container Water Gardens

For patios or small spaces, container water gardens allow you to enjoy aquatic plants without a full pond. Use compact species like Alternanthera sessilis or dwarf water lilies to create portable, colorful focal points.


Care Tips for Healthy Purple Water Plants

  • Sunlight: Most purple water plants require full to partial sunlight for optimal flowering. Check species-specific needs before planting.
  • Water Quality: Keep the water clean and free from excessive algae. Submerged plants naturally help maintain water clarity.
  • Fertilization: Use aquatic plant fertilizers to support strong growth and vibrant blooms.
  • Pruning: Remove dead or decaying foliage regularly to encourage healthy development and prevent disease.
  • Winter Care: Some species need overwintering indoors or protective measures during colder months.
