Dalmatian toadflax was introduced to the United States in the late 1800s as an ornamental species because of its showy flowers. Other common names include Butter and Eggs and Wild Snapdragon.

Dalmatian toadflax is an upright perennial forb that reproduces by seed and creeping rootstocks. Its deep taproot and extensive horizontal root system make the plant efficient in capturing water, resprouting after fire, and withstanding grazing.

An aggressive spreader, large infestations can significantly reduce rangeland forage value. Although typically avoided by cattle, Dalmatian toadflax contains a poisonous compound, glucoside, that if ingested in large quantities is harmful to livestock and wildlife.
