Nymphaea ‘Siam Purple’ is a captivating member of the Nymphaeaceae family, known for its stunning purple blooms and enchanting fragrance. This hardy water lily is the result of a successful crossbreeding between a hardy and tropical water lily, combining the best traits of both varieties. With its striking star-shaped flowers and vibrant coloration, Nymphaea ‘Siam Purple’ adds a touch of elegance and beauty to any water garden or pond.
From the months of June to September, Nymphaea ‘Siam Purple’ showcases its magnificent blooms, drawing attention with their deep purple petals that gradually transition to lighter shades of purple and pink towards the center. The flowers measure approximately 15cm or 6 inches in width, making a bold statement amidst the aquatic foliage. The star-like form of the blooms, combined with their sweet and alluring fragrance, creates a truly captivating sensory experience.
This winter-hardy hybrid exhibits round green leaves that emerge with a captivating purple hue, further enhancing the visual appeal of the plant. As the leaves mature, they transition to their characteristic green coloration, providing a lush backdrop for the vibrant blooms. Nymphaea ‘Siam Purple’ offers a pleasing contrast between its colorful flowers and the deep green foliage, making it a standout feature in any water garden or pond landscape.
When it comes to cultivation, Nymphaea ‘Siam Purple’ thrives in both full sun and partial shade, making it versatile and adaptable to different lighting conditions. Planting it at a depth of approximately 45cm or 18 inches ensures optimal growth and development. Regular maintenance is essential for the plant’s well-being, including the removal of dead or yellowed leaves and spent flowers. Pruning should be done by cutting the foliage and flowers, avoiding pulling them, which can cause damage to the plant.
During the growing season, Nymphaea ‘Siam Purple’ benefits from regular fertilization, providing it with the necessary nutrients for healthy growth and abundant blooms. However, once the leaves die down and the dormant season begins, typically during winter, minimal care is required. It is during this period that the plant can be protected from freezing temperatures by either moving potted water lilies indoors or implementing pond winterization techniques.
Nymphaea ‘Siam Purple’ exemplifies the beauty and resilience of hardy water lilies, combining exquisite purple flowers, attractive foliage, and a delightful fragrance. Whether it graces a tranquil pond or a carefully designed water garden, this enchanting water lily variety adds a touch of elegance and serenity to any aquatic landscape, making it a cherished focal point for nature enthusiasts and water gardening enthusiasts alike.
Planting:
Water Depth and Quality: Nymphaea ‘Siam Purple’ thrives in still or slow-moving water with a depth of 12 to 36 inches (30 to 90 cm). Maintaining suitable water quality is important for the health and growth of the water lily. Ensure that the water is free from pollutants and excessive algae, as clean water promotes optimal growth. Regular water changes and the use of a filtration system can help maintain favorable water conditions.
Soil and Planting: When planting Nymphaea ‘Siam Purple,’ follow these guidelines for successful cultivation:
- Aquatic Soil: Use aquatic soil or loam soil specially formulated for aquatic environments. This type of soil retains nutrients while allowing water circulation. Avoid using regular garden soil or potting mix, as they may become compacted and hinder root growth.
- Planting Depth: The rhizomes or tubers of Nymphaea ‘Siam Purple’ should be planted at a depth of approximately 45 cm or 18 inches below the water surface. Ensure the crown of the plant is level with the soil surface. Adjust the planting depth to match the specific recommendations for your water lily variety.
- Container or Pond: Nymphaea ‘Siam Purple’ can be grown in containers or natural ponds. If using a container, choose a spacious one that can accommodate the mature size of the plant and has adequate drainage holes. Place the container in the desired location within the pond, ensuring it is submerged to the appropriate planting depth.
Light and Temperature: Nymphaea ‘Siam Purple’ thrives in full sun to partial shade. Provide at least six hours of direct sunlight each day for optimal growth and flowering. However, in extremely hot climates, some shade during the hottest part of the day can help protect the plant from excessive heat stress. This water lily is a winter-hardy hybrid, tolerating colder temperatures.
Fertilization: Regular fertilization during the growing season can promote vigorous growth and abundant flowering. Use a fertilizer specifically formulated for aquatic plants and follow the manufacturer’s instructions for application rates. Typically, water lilies are fertilized every two to four weeks during the active growing season. Avoid over-fertilizing, as it can lead to excessive algae growth.
Keep Nymphaea ‘Siam Purple’ healthy and blooming:
Deadheading: Remove faded or spent flowers by cutting the stem just above the water surface. This prevents the plant from expending energy on seed production and encourages more blooms.
Leaf Pruning: Trim dead or yellowed leaves close to the base of the plant. Use clean, sharp tools to make precise cuts. Avoid pulling or tearing the leaves, as this can damage the plant.
Dormant Season: During the dormant season, which typically occurs when the leaves die down, the water lily enters a period of rest. At this time, minimal maintenance is required. Monitor the water temperature and stop fertilizing once the plant enters dormancy.
Pest and Disease Control: Monitor for common pests such as aphids or water lily beetles. If necessary, employ appropriate pest control measures. Ensure good water circulation and avoid stagnant conditions to prevent disease issues.
Winter Protection:
In regions with freezing temperatures, it is crucial to protect Nymphaea ‘Siam Purple’ during the winter months. Here are some recommendations for winter care:
- Pond Winterization: If your water lily is planted in a natural pond, it is advisable to winterize the pond to prevent freezing. As winter approaches, gradually lower the water level to reduce the risk of freezing. Insulate the pond by covering it with a floating net or placing a protective barrier over the water’s surface. This helps to retain heat and prevent extreme temperature fluctuations.
- Moving Potted Water Lilies: If you have Nymphaea ‘Siam Purple’ planted in containers, you can take them indoors for the winter. Before the first frost, carefully lift the potted water lily from the pond. Trim back any remaining foliage, leaving only a few inches of stems. Place the potted water lily in a cool, dark place indoors, such as a basement or garage, where the temperature remains above freezing but stays around 40-50°F (4-10°C). Ensure the plant receives minimal light during this dormant period.
- Overwintering in Aquatic Tanks: Another option is to overwinter Nymphaea ‘Siam Purple’ in large aquatic tanks or containers indoors. Fill the tanks with water, and place the potted water lilies inside. Position them near a window or under grow lights to provide a small amount of light. Maintain the water temperature around 40-50°F (4-10°C). During this period, the plants will enter dormancy, and growth will significantly slow down.
- Monitoring and Maintenance: While the water lilies are in their winter resting phase, periodically check the water level to ensure it remains sufficient. Avoid allowing the plants to dry out completely. Monitor for any signs of pests or diseases, and take appropriate measures if necessary.
- Spring Transition: As spring approaches and the risk of frost diminishes, gradually reintroduce Nymphaea ‘Siam Purple’ to the outdoor environment. Place the potted water lilies back into the pond or move them to a sunny location. Resume regular care and maintenance practices, including fertilization, as the plants come out of dormancy.
By providing the necessary winter protection, you can help ensure the survival and healthy growth of Nymphaea ‘Siam Purple’ in regions with freezing temperatures.
