100 Pampas Grass Seeds (Cortaderia selloana)
Pampas grass is a large, clump-forming perennial ornamental grass known for tall, feathery plumes that appear from late summer into fall. Mature plants create a strong architectural accent, and the plumes can be used in cut or dried arrangements.
Seed-grown variation: Plants raised from seed can vary in plume shade, height, and form. The selected color identifies the seed option ordered but does not guarantee an exact mature shade.

Important Before Planting
Cortaderia selloana is invasive or regulated in parts of the United States. Check current state and local rules before ordering or planting. Avoid planting near natural areas, and remove and bag flower plumes before seed dispersal where spread is a concern.
Mature leaves have very sharp edges. Wear sturdy gloves, long sleeves, and protective clothing when handling or pruning established plants.
Planting Instructions
- Fill a tray or small pots with a moist, fine seed-starting mix.
- Press the seeds onto the surface. Do not cover them heavily because light supports germination.
- Keep the mix evenly moist but not waterlogged in a warm, bright location.
- Provide good airflow and continue bright light after seedlings emerge.
- Transplant established seedlings outdoors after frost risk has passed, allowing ample room for mature growth.
Germination and time to flowering vary with temperature, light, moisture, and seed lot.
