Not really a problem in my yard, since I have a yard as opposed to a lawn. My philosophy is live and let live, although someone who gets into a perfect carpet of uniform green could get agitated by this plant.

Originally from Europe, and Little Hop Clover (T. dubium) is somewhat famous as a contender for recognition as the Irish Shamrock.
