Linaria vulgaris, also known as the common toadflax, yellow toadflax, or butter-and-eggs, is a species of flowering plant in the family Plantaginaceae, native to Europe, Siberia and Central Asia. It has also been introduced to and is now common in North America. It is a perennial plant with short spreading roots, a stem height of 15 to 90 centimetres (6 to 35 inches), and fine glaucous blue-green leaves. The flowers are pale yellow with an orange lower tip, borne in dense terminal racemes from mid-summer to mid-autumn, and visited mostly by bumblebees. Its fruit is a globose capsule containing numerous small seeds. The species is most commonly found as a wildflower, toadflax, but is sometimes cultivated as a cut flower or in children's gardens. These L. vulgaris flowers were photographed in Keila, Estonia. This picture was focus-stacked from 30 separate images.Photograph credit: Ivar Leidus
