Creeping spikerush (Eleocharis palustris) is a low-growing perennial plant that belongs to the Cyperaceae family. It is characterized by its slender, grass-like stems that spread horizontally, forming dense mats over wet soil or shallow water. Creeping spikerush is a low-maintenance plant that adds a lush, grassy texture to wetland gardens, pond margins, and other water features. With proper care, it can spread to form attractive ground covers while providing habitat for various wildlife species.
- Size: Height: Up to 12 inches (30 centimeters). Spreads horizontally to form dense mats.
- Light: Creeping spikerush thrives in full sun to partial shade. Provide at least 6 hours of sunlight per day for optimal growth.
- Water: This plant prefers consistently moist to wet soil. It can tolerate shallow water up to a few inches deep, making it suitable for planting in bog gardens, around ponds, or in rain gardens.
- Soil: It grows well in a wide range of soil types, including clay, loam, and sandy soils, as long as they are consistently moist.
- Fertilizer: Creeping spikerush generally does not require fertilization if planted in nutrient-rich soil. However, if growth seems slow or the soil is poor in nutrients, you can apply a balanced, slow-release fertilizer in spring.
- Pruning: Pruning is typically not necessary for creeping spikerush, but you can trim back any dead or damaged foliage to maintain its appearance.
- Propagation: This plant can be propagated by dividing mature clumps in spring or early summer. Simply dig up a portion of the clump, ensuring it has both roots and stems, and replant it in a suitable location.
