Photograph of a close-up of a specimen of Matilija poppy (Romneya coulteri), ca.1920. On dark background.; "These lovely perennials are natives of California and Mexico and belong to the Poppy family, Papaveraceae. There are only two varieties of Romneya. One is R. Coulteri, the Matilija Poppy, and the other is R. trichocalyx; they are sometimes known as Tree Poppies. The latter differs very slightly from the first. The Matilija Poppy grows from 5 to 6 feet tall and has deeply divided, blue gray leaves. Large, white, fragrant flowers are produced in the summer; the petals resemble crL pe paper and they surround a tuft of golden stamens. R. trichocalyx usually blooms a little more than R. Coulteri." -- unknown author.
