This species both self-sows weedily and also spreads underground aggressively by rhizomes.

The Florida Exotic Pest Plant Council has listed this species as a Category l invasive, because it has been found to invade natural areas and displace native flora. The species is native to Mexico, South America, and the Caribbean. It has naturalized from Texas to South Carolina.

This Ruellia like many can self sow with abandon and spread by running rootstocks.
Best to contain it with a solid barrier unless you have lots of room for it to fill. Tolerates clay and flooding.
