Yellow wildflowers of west and southwest USA: Linaria vulgaris: common toadflax, butter-and-eggs, yellow toadflax: Plantain family (Plantaginaceae). Yellow Toadflax can displace existing plant communities and desirable plants, cause loss of forage for domestic livestock and some big game, and reduce habitat for associated native animals. The problem with this plant is that, once established, yellow toadflax suppresses other vegetation mainly by intense competition for limited soil water. These flowers give the plant its other common name of 'Butter and Eggs'. Germination usually occurs in the top 2 cm of soil Dormancy: Seeds may germinate immediately or may remain dormant up to 8 years. Yellow toadflax is easily confused with leafy spurge before flowering, but toadflax stems do not contain the milky latex that spurge does.
