Dalmatian Toadflax, a member of the snapdragon family, was introduced as an ornamental plant and is a noxious weed in Wyoming. Flowers are bright yellow with two ‘lips’ and spurs at the bottom. Even from early stages, Dalmatian Toadflax can be distinguished from Yellow Toadflax by the broad heart-shaped leaves that clasp the woody stems.

Dalmatian Toadflax rosettes exhibit the wide, heart-shaped leaves that distinguish it from Yellow Toadflax.
