This perennial weed grows to two feet tall.
Leaves are two and one-half inches in length, narrow, and pointed.
Yellow toadflax came from Eurasia. It is an aggressive invader of rangeland, roadsides, field edges, and waste areas. An extensive root system makes this weed difficult to control. It reproduces by seeds and roots.
Flowers are about one inch long, yellow with an orange throat, and have long tails. They look similar to snap dragon flowers. Bloom is in late spring into summer.
