Asteraceae is one of the largest of plant families; it includes many flowers of similar appearance - densely packed heads comprising many tiny flowers or florets (hence the old family name Compositae meaning 'composed of many little flowers'). The internal florets are symmetrical with tiny petals, while each of those at the edge - the so-called 'ray florets' - have mostly tiny petals but one large petal facing outwards. The name Asteraceae refers to the star-like form of the inflorescences. These thumbnail pictures have links to larger photographs and information about each of the species, their habitat needs and an identification guide.
