Wiregrass (Aristida stricta) is a warm-season bunchgrass of southeastern North American pine savannas and sandhills, forming dense tufts of wiry leaves and tall three-awn seed heads that catch light. It is a keystone species in fire-maintained longleaf systems, providing fine fuel and structure for wildlife. Heights of 2–4 feet (60–120 cm) are typical; roots dive deep on sand. ☀️💧 Sun and Water Requirements: Full sun; shade reduces vigor. Deep, well-drained sandy soils are native truth; tolerates drought once established. Avoid heavy clay and chronic irrigation. ✂️ Propagation: Sow seed in warm soil; establish from local ecotype sources for restoration integrity. Burn management follows regulations—never freestyle fire without training. 🌾 Harvest / Best Use Timing: Primarily ecological—seed for restoration; leave standing for wildlife cover. Peak growth follows warm wet periods.

Good Neighbors
  • Longleaf Pine — overstory pine in classic wiregrass savanna where both belong ecologically
  • Little Bluestem — complementary warm-season grass texture in mixed ground layers
  • Milkweed — forb neighbor for pollinator strips at savanna edges
Cautions
  • Fire ecology — growth assumes periodic burn in many natural systems; follow laws and safety
  • Wrong soil — clay makes wiregrass a short tragic play
