Sida rhombifolia is found occasionally on ballast in New Jersey and Pennsylvania. It is a common weed in warm-temperate, subtropical, and tropical areas; its genetic diversity seems to indicate that it was introduced from the Old World. The species has been cultivated for medicinal and cordage use.
