About Diaperia verna (Raf.) Morefield
Diaperia verna, which has the common names spring pygmycudweed, spring rabbit-tobacco, and many-stem rabbit-tobacco, is a plant species belonging to the sunflower family. It is native to northern Mexico, ranging from Sonora to Tamaulipas, and the southern United States, ranging from Arizona to Louisiana. Isolated populations, possibly introductions, are also found in Alabama, Georgia, and South Carolina. Diaperia verna is an herb, and its leaves appear greenish or grayish because of a coating of woolly hairs. A single plant usually produces several flower heads, where the corollas are hidden by surrounding bracts. Two varieties are recognized: Diaperia verna var. drummondii (Torr. & A.Gray) Morefield, which occurs in coastal Alabama and Texas; and Diaperia verna var. verna, which is found in Arizona, Arkansas, Georgia, Louisiana, New Mexico, Oklahoma, South Carolina, Texas in the United States, and in Chihuahua, Coahuila, Nuevo León, Sonora, Tamaulipas in Mexico.
