Origin:

Native to Europe, but introduced to the United States as a garden ornamental, and now found in California, Oregon, Idaho, and several states in the area of Pennsylvania.

Biology:

An annual weed that reproduces from seeds. Plants may be found along roadsides and in other disturbed sites. They are similar to Dalmation Toadflax but are a much less serious problem, due to their much slower spread and lower habit. Linaria species also tend contain poisonous glucosides that can be toxic to livestock.

Identification:

Mature plants tend to grow more prostrate and sprawling, remaining close to the soil. Stems can grow to 2 feet long, and are lined with the closely spaced, alternating leaves. These clasp the stem at their base, are lance shaped and pointed, and are broader at their base. Numerous short branches grow off of the main stems. Flowers are produced along the elongating ends of the stems and are bright yellow, snapdragon shaped, and with a long, pointed lower petal.

Characteristicts Important to Control:

A contact or systemic herbicide will effectively kill this weed.
