Greater Tussock-sedge
Carex paniculata · Cyperaceae
Panicled sedge is a robust aquatic grass that thrives in permanently wet environments. It is valued for its elegant, arching foliage and delicate spring flowering. This hardy, low-maintenance perennial is perfect for water gardens, pond margins, and naturally wet areas. Its dense root system helps stabilize banks and retain sediment, making it an excellent choice for ecological restoration projects.

Care
Watering
Panicled sedge loves constantly moist to wet soil. Keep moisture levels consistent without letting the soil dry between waterings. In dry regions, water generously in spring and summer. In naturally humid settings or near a pond, additional watering becomes unnecessary.
Light
Place this sedge in part shade or full sun depending on your climate. It tolerates part shade well and remains lush there. In warm climates, partial shade prevents water stress. It is not demanding about light but benefits from good brightness to maintain a compact silhouette.
Soil
Choose soil rich in organic matter, silty or clay-based, and especially very moist. This species adapts to poor soils but thrives best in amended ones. It tolerates pond margins, wet ditches, and seasonally flooded areas very well.
Pruning and maintenance
Perform light cleanup in spring by removing dead or damaged foliage. Cut back the clump in late winter (February–March) to rejuvenate it. This sedge does not require heavy pruning: simple combing suffices to maintain its graceful form.
Fertilizer
Panicled sedge is not demanding and requires no regular fertilizer. An application of compost or organic matter in autumn or early spring boosts growth. Avoid excessive nitrogen fertilizers, which may weaken the plant.
Pests and diseases
This sedge is very robust and rarely affected by disease. In overly dry soil, it may experience mild cosmetic stress. Watch for yellowing if roots are suffocating or rotting in overly saturated, stagnant conditions. Good air circulation prevents these issues.
Did you know?
Panicled sedge was historically used for natural liming and bank stabilization across central Europe. Its dense, interwoven root system effectively retains sediment, making it invaluable for restoring degraded wetlands. Its Latin name 'paniculata' refers to its panicle-like flower clusters, a rare trait among Carex species.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
