The plant big quaking grass exhibits a widespread geographical presence, being native to the Mediterranean basin and parts of southwestern Europe. It has been introduced across various continents including Asia, Africa, and the Americas, due to its cultivation or incidental spread. While big quaking grass is cultivated in certain areas for its ornamental value, it may have an impact on local ecosystems when growing outside its natural range, especially in regions like Oceania and parts of Central and South America, where it is sometimes thought to be invasive. The degree of its impact in non-native regions, however, often varies and is subject to ongoing examination.
