A perennial plant of the Asteraceae family, with around 30 species found in South Africa. The flowers are flower heads similar to daisies, but the stems and leaves are covered with short white hairs. The flower heads are beautiful with large, developed ray petals. Young flowers open during the day but close at night. The genus name means "bear's ears" in Greek, referring to the way the seeds are wrapped in fluff. The species usually cultivated are hybrids of A. grandis Thunb. (African daisy), and the flowers are white, cream, yellow, orange, red, wine-colored, etc., measuring 7-8 cm in diameter and with unusual colored spots at the base of the petals.
