Thistles are erect annual, biennial, or perennial herbs, which reproduce by seed. The flower heads are generally reddish to purple although yellow flowers are produced by some species. Seeds germinate mainly after the autumn rains but a few shoot at other times when adequate moisture is available. They grow in winter developing further in spring and flowering in summer to late autumn.
