Growing Prairie Dropseed (Sporobolus heterolepis) from Seed in Zone 5

Cold-Moist Stratification for Native Grass Seed

Prairie dropseed benefits from 30–60 days of cold, moist stratification.

Protocol

  1. Place seeds in a damp cloth; seal in a plastic bag.
  2. Refrigerate 30–60 days (January–March for Zone 5).
  3. Press seeds into soil surface; barely cover.
  4. Keep at 75°F (24°C); germination in 10–21 days.
  5. Grow under lights until after last frost; harden off 10 days; plant in full sun.

This warm-season grass forms elegant fountain-like clumps and is drought-tolerant once established.
