Snake root, Calla Palustris: a striking aquatic plant
Snakeweed, Calla palustris, is a striking, native aquatic plant ideal for wet, shady garden spots.
Where does Snake Root grow?
Snakeweed is found mainly in moist, wetlands. It is an ideal plant for marshes, along ponds and in wet garden areas. In the Netherlands, Snakeroot is often found in wetlands and is also suitable along the pond edge in the garden.

Tips, advice and substantial savings
Characteristics of Calla palustris
Snakeroot is characterized by its glossy, heart-shaped leaves and the striking white flower calyxes, which are actually bracts surrounding the actual flowers. This plant can reach a height of about 30 cm. Flowering occurs in late spring and early summer. Snakeroot also forms red berries after flowering, which, however, are poisonous.

Benefits of Snake root in the garden
In addition to its decorative value, Snake Root also provides habitat for various aquatic animals and insects, contributing to a rich biodiversity in your garden. The plant is relatively easy to maintain and is perfect for creating a natural water environment.
Disadvantages of this plant
One challenge in growing Snakeroot is its need for consistently moist conditions. The plant does not tolerate drought well and requires a location with plenty of water. It is also important to note that all parts of the plant are toxic if ingested.
Care and maintenance of Snake Root
- Location and soil preference.
Snakeroot prefers a spot in partial or full shade, with consistently moist, humus-rich soil. The plant is ideal for pond edges or in wet areas of the garden. - Water needs
This aquatic plant has a continuous need for moisture. Make sure the soil around Snake Root is always wet, but avoid flooding the plant for extended periods. - Pruning and maintenance
Snakeroot requires little maintenance. Remove dead leaves and spent flower calyxes to keep the plant tidy and provide room for new growth. - Winter hardiness and overwintering.
Snakeroot is reasonably hardy. In harsher winters, you may need to protect the plant from frost, especially if it is growing in a pot. - Nutrition and fertilization.
Light fertilization in the spring can promote the growth of Snake Root. Use a fertilizer suitable for aquatic plants.
Conclusion
With its unique flowers and heart-shaped leaves, Snake Root adds a special atmosphere to any pond. Although care is simple, it is important to consider the plant's moisture requirements and toxicity. The plant can cause skin irritations and/or allergic reactions. Therefore, be careful with pets and children.
