Yellow Toadflax is native to Eurasia and was introduced to places like North America as an ornamental and great source for yellow clothing dye. It is a pretty flower that is still sometimes used in flower gardens but it can escape and is very aggressive.

Yellow Toadflax will take over and displace desirable grasses and plants. Once established, Yellow Toadflax is very difficult to eradicate because of its extensive root system. On top of all this, it is suspected of being mildly poisonous to livestock.
