Hedgehog Sedge Plant Care

Hedgehog Sedge (Cyperus echinatus) belongs to the Cyperaceae family within the Cyperus genus. Hedgehog Sedge is native to much of the eastern United States, primarily in the lower Mississippi Valley and the lowland plain east of the southern Appalachians, with scattered populations in Florida and as far north as Wisconsin and the Adirondacks. Hedgehog Sedge is also known as Sedge.

Hedgehog Sedge displays a grassy, clumping perennial growth habit, reaching up to 2 ft tall with a spread of approximately 1.5 ft. Hedgehog Sedge produces small, inconspicuous flowers in clusters.

Leaf size: approximately 12 inches.

Cyperus echinatus requires watering every 3–5 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Hedgehog Sedge thrives in bright indirect light. Avoid placing Hedgehog Sedge in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Cyperus echinatus grows best at temperatures of 60–80°F. Hedgehog Sedge prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, moist soil with good drainage. Good drainage is essential for Hedgehog Sedge to prevent waterlogging, which leads to root rot and fungal issues.

Feed Hedgehog Sedge every 6 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Repot every 1-2 years in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Hedgehog Sedge can be propagated through division, seeds. Similar propagation techniques also apply to clustered flatsedge plant care, which shares the same genus.

Hedgehog Sedge is susceptible to aphids, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Hedgehog Sedge grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Hedgehog Sedge is native to much of the eastern United States, primarily in the lower Mississippi Valley and the lowland plain east of the southern Appalachians, with scattered populations in Florida and as far north as Wisconsin and the Adirondacks. In cooler regions, grow Hedgehog Sedge as a houseplant or bring it indoors before the first frost.
