Yellow toadflax Linaria vulgaris
A Class C noxious weed in Washington State, yellow toadflax thrives predominately along roadsides, trails, railroads and open fields. It is occasionally found in gardens and landscapes. Its yellow flowers resemble that of a snapdragon, and are very similar to the flowers of Dalmatian toadflax. The leaves of yellow toadflax are small, narrow and linear, and the overall plant is seldom over 8 inches tall. Control of yellow toadflax in King County is recommended but not required.
