Pampas grass seeds are small and narrow, with a dark brown to black color. They are long and pointed, with a slightly curved shape and a hard, shiny surface.

The seeds are enclosed in small, fluffy plumes that form at the top of the plant in late summer or early fall. As the plumes mature, the seeds are released and can be dispersed by the wind or other means.

Planting Pampas grasses is as easy as planting other plants or crops in your garden as you can conveniently grow it from its seeds. You only need simple materials and a fertile soil to grow it.

Each plume of this grass has the capacity to hold up to 100,000 seeds which causes it to grow and scatter fast.
Moreover, the female pampas grass produces more seeds than the male ones. You can identify the female grass by the size and fluffiness (bigger and fluffier) of their plumes.
