Discussion Also known as Wallace's woolly daisy, Wallace's woolly sunflower, Wallace woolyleaf, woolly easterbonnets. In desert annuals, such as Woolly Daisy, seed production is vital for yearly survival. During drought plants often grow only about 1/4 (6 mm) before producing one head, ensuring at least some seeds. Under moister conditions plants repeatedly branch near the base, producing taller stems, many heads, and abundant seed.
