The native range of
C. selloana includes Argentina, Bolivia, Brazil, Chile, Paraguay, and Uruguay. This region is dominated by subtropical forests and grasslands, but
C. selloana is typically restricted to moist soil within
riparian areas. It is found at lower elevations and at moister sites than the closely related
C. jubata. It requires areas with plentiful light and soil moisture. It is a common invasive species in temperate regions around the world, where it can be found growing in moist, disturbed soil.
Control Pampas grass can be controlled through herbicide treatment. To accomplish this, the grass is cut down near the base. Next, a 2% glyphosate chemical solution is combined with a silicone-based surfactant and applied to enhance the penetration potential. This method works best in the fall because there is overall better control compared to other seasons. Another control method is to cut and bag inflorescences to prevent seeds from spreading or pulling seedlings. ==Cultivation==
