He liked it, and established it on his land where it grew thick and fast. From there, it has spread all over the southeastern quadrant of the United States and can be found in spots as far west as Texas and even California. It thrives on any patch of disturbed soil it can find, whether plowed or bulldozed or just overworked. A single plant produces up to 5,000 seeds per year, and those seeds can lie dormant in the ground for up to twenty years to come. This perennial grass has fleshy rhizomes that easily break into live pieces of viable roots, rendering persistant mechanical removal extremely necessary. Make sure to get all fleshy rhizomes.
