A native plant of the eastern US, hedge bindweed is considered invasive in several US states, including Alaska, Michigan, Ohio, and Washington. It can now be found all across the world, having been cultivated for its delicate, trumpet-like flowers. However, it has proven to be quite the pest, being difficult to manage with its deep roots, copious rhizomes, and aggressive spreading. Elimination is nearly impossible and with hedge bindweed's quick growth along the ground, it has become problematic for crops. Its seeds and roots are also slightly poisonous. Continuous removal of roots over several seasons is one of the few ways of controlling this weed.
