Eremochloa ophiuroides
centipede grass
Southeast Asia (China); introduced to the US in 1916
Overview
Eremochloa ophiuroides is centipede grass (centipedegrass), a warm-season perennial spreading grass growing 2-6 inches (5-15 cm) mowed height. Apple-green to light green medium-textured blades 2-4 mm wide. Spreads by stolons (above-ground runners) only — no rhizomes. In the grass family (Poaceae spp.). The apple-green color is lighter than Bermuda or zoysia. Warm-season: grows actively at 75-90°F (24-32°C). Goes dormant (turns brown) below 55°F (13°C). Requires acid soil pH 5.0-6.0 — the primary limitation. Chlorosis (yellowing) occurs above pH 6.5 due to iron deficiency in alkaline soils. The lowest-maintenance warm-season lawn grass in the southeastern US: mow infrequently at 1.5-2 inches (4-5 cm), no fertilization needed on acid soils, low water requirement. Slow to establish from seed (2-3 years to full density). Not traffic-tolerant — does not recover from heavy wear. Sensitive to herbicides — many common lawn herbicides damage centipede grass. Zones 7-10. Drought-tolerant once established. Non-toxic. Perennial. Growth rate is slow.

Detailed Descriptions
Foliage Description
Apple-green to light green, medium-textured blades 2-4 mm wide; lighter green than Bermuda or zoysia — the apple-green color is the species' defining visual traitGrowing Conditions

Requires 5-12 hours of direct sunlight daily
• Full Sun: 6+ hours of direct sunlight
• Partial Shade: 3-6 hours of direct sunlight
• Full Shade: Less than 3 hours of direct sunlight
Care & Maintenance
Care Guide
Full sun to partial shade (5+ hours). Acid soil pH 5.0-6.0 — chlorosis above pH 6.5. Mow at 1.5-2 inches (4-5 cm) infrequently. No fertilization on acid soils. Sensitive to many herbicides. Not traffic-tolerant. Dormant (brown) below 55 degrees F (13 degrees C). Zones 7-10. Perennial.Pruning
Mow at 1.5-2 inches (4-5 cm). Mow infrequently — centipede grass grows slowly. Do not scalp. No dethatching unless thatch exceeds 0.5 inch (1.3 cm). Do not overfertilize — centipede decline results from excess nitrogen.Pruning Schedule
